How many email addresses can you send at once?

How many email addresses can you send at once?

If you're using any kind of service that doesn't allow unlimited messages sent, like Facebook or Twitter, it might seem strange that your email provider allows so much. But there's actually a good reason behind this limit—spammers are known to use these services as their main method of distributing junk mail.

However, if you want to be able to receive and send large amounts of email without breaking the system, here's what you need to know about how many email addresses you can add to one message.

How many email addresses can you put in one email?

When sending out mass emails through Gmail, Hotmail, Yahoo Mail, etc., each recipient gets only one address in the "From" field. This means that if you wanted to send out an email with 500 different addresses in the From field, it would fail. However, if you were sending all those emails to the same person (or group), you could technically split them up into smaller groups. For example, say you had someone who was in charge of managing 500 separate mailing lists for work. You could give him/her two addresses instead of just one. The first address would then go on his personal account, while the second would go onto a list-specific account. Then he/she could manage both simultaneously within the application.

Of course, splitting things up like this requires some sort of organization structure already set up, which may not always be possible. If you don't mind having a single From address, though, you should be fine.

In addition, because most users will likely see more than one email coming from the same address, they'll probably wonder why you didn't include other information like name or subject line. So if you really want to avoid confusion, make sure you vary the name and subject lines of every individual email. That way, even if you end up with too few fields, no one will think twice about receiving an email from "Dear Mr. Smith".

Can an email have multiple from addresses?

Yes! In fact, it's pretty common for companies to create several aliases for the same user. Maybe you have more than one job title but still want to appear under the company email address. Or maybe you'd prefer to communicate via email when working remotely rather than over IM. Whatever your situation, creating alias email addresses is easy enough thanks to Google Apps' settings. Just visit and click on Manage Aliases.

You won't find this option anywhere else in the world — unless you've paid $50+ for Microsoft Office 365 Business Premium ($5 monthly fee) or are running Windows Server 2003 R2 Standard Edition ($299). Both options come equipped with a similar feature called Email Addresses. It lets administrators assign up to 250 email aliases to specific users, allowing them to log into Outlook Web Access to check or respond to messages. Of course, we recommend sticking to free methods whenever possible.

Now that you know how to create custom aliases, let's talk about how you can send multiple From addresses in Gmail.

How do I send an email to 500 people?

The simplest solution is to simply type everyone's email address directly into the To field. Obviously, this isn't practical if you plan to hit the 500 mark soon. Luckily, there are plenty of tools available online that let you quickly generate a spreadsheet containing hundreds of email addresses. There are also several web apps designed specifically for bulk emailing. We tested three popular ones below, along with our own recommendation.

Mail Merge by Spreadsheet123 [No Longer Available]

Mail Merge by Spreadsheet123 has been around since 1997, making it one of the oldest services on offer today. Its biggest selling point is its ability to automatically fill in data such as names, addresses, phone numbers, dates, and credit card details. Users can also customize templates based on their needs. All you have to do after downloading the template file is open it in Excel and copy and paste the contents into Word.


A wide variety of features including auto responders, autoresponders, HTML formatting, and attachments.


It takes forever to send out massive batches of emails due to server load. Also, if you don’t organize your contacts properly, you may end up accidentally CCring yourself in on certain conversations.

Email Hunter

Like Mail Merge, Email Hunter offers automatic contact management. What makes it stand apart, however, is its interface design and ease of use. Instead of entering addresses manually, you choose which category they belong to before clicking “Send Emails”.

Using this tool, sending 500 emails couldn’t be easier. One downside of this app compared to others is that it does require Flash Player 9.0 installed. Other than that, it works great and provides tons of useful features.


Ability to import existing contacts, auto-fill info, customizable templates, advanced filters, and mobile versions.


Only supports 300 recipients per batch. No support for images embedded in emails.

Bulk E-Mail Generator

This handy little program generates spreadsheets filled with thousands of e-mails in seconds. Once you download the.exe file, double-click it to launch BulkEPGW32.exe. Next, select either CSV or TXT format. After choosing your preferred output, click Create File. A new window will pop up asking you where you’d like to save the file. Save it wherever you wish. Now close the program. When you reopen BulkEPGW32.exe, you’ll notice that the source dropdown menu now contains your newly created excel file. Select the appropriate tab and begin adding your contacts. Each row represents one recipient in your document. Simply enter the necessary information and click OK. Repeat until complete. Finally, run the program again, selecting the destination folder button. Your spreadsheet will immediately update itself and you can proceed to opening the generated files in MS Excel to edit.


Generates spreadsheets full of dozens of addresses in minutes.

Allows users to easily print labels.

Supports importing contact lists.


Doesn’t provide instructions on how to convert text columns to headers.


As long as your friends aren’t tech geeks, chances are good that they won’t realize that you used automation software to send them all those emails. And if your boss ever catches wind of your activity, well…let’s hope you have a solid explanation ready. Otherwise, feel free to try out these programs and tell us what you thought about them. Did one of them meet your expectations? Which did you like best? Let us know in the comments section below...

If you've been using a computer for more than five minutes, chances are you're familiar with how annoying it is when your inbox fills up. If you have multiple email addresses, this problem gets even worse as people will have trouble finding what they need if there's too much clutter. Fortunately, Google has developed some pretty strict rules on which types of email address are allowed to be used together.

In order to understand these guidelines, let’s talk about spammers first. Spamming refers to sending unsolicited commercial emails (spams) to random people. This type of action is illegal in most countries so businesses that engage in spamming activities face hefty penalties from their local regulators.

When spammers want to create new user accounts, they typically buy them from hackers who sell lists containing hundreds or thousands of email addresses. Once spammers receive such bulk email addresses, they can use those addresses to send out millions of messages without being flagged by email filters. To avoid getting caught, most companies don't allow users to register under several different email addresses.

So why does Gmail limit the amount of people you can email at once? One reason is because it helps protect against spam. When someone sends an email to 1 million users, it could take days before all of the mail servers detect the flood of incoming traffic. The longer it takes for everyone to see the message, the harder it would be to filter out the junk.

Another good reason is that every time you add another account you increase your risk of having your own mailbox flooded with unwanted messages. Some unscrupulous scumbags may try to trick unsuspecting victims into giving away their email addresses. Since each email address is considered like a password, adding extra ones increases the likelihood of phishing attacks.

The final reason to restrict the number of email addresses you can use is security concerns. Email clients often store information such as passwords and private encryption keys inside the client itself rather than storing them online. In other words, if you lose access to your email account, you'll also lose control over its contents. Therefore, most major providers require users to only sign up with a single account.

Now that we know why companies implement policies limiting the number of free email accounts you can open, let's discuss ways around these limitations.

How many email recipients can I send to at once Gmail?

Gmail allows you to set the maximum number of recipients you'd like to invite to any given event. For example, you may decide to host a party where you plan to give away 10 invites instead of just 5. By doing so, you won't have to worry about flooding your contacts' inboxes later on. You can always remove people after giving them the chance to attend.

Here's how to change your setting: Open your profile page and click "Settings" located right underneath the "Account Settings" header. Now select "Invitations."

You should now find yourself in the settings of invitations. Change the dropdown menu next to "Max # Recipients," then choose whether you'd like to go back to the default value ("5") or raise it higher.

Once done, hit save changes and wait until your invitation link shows up in your email signature. That way anyone who receives your e-card will automatically become part of your group.

Note: Please note that while inviting guests through Gmail works great for events, you cannot simply start bombarding people with mass emails unless you have previously agreed to participate in such things. Violating this rule may result in termination of service.

How do I send an email to 500 recipients in Gmail?

There are actually two ways you can accomplish this task. First, you can send individual mails to the same list of people but make sure not to exceed Gmail's daily limit. Second, you can ask your friends to forward your email to others. However, since forwarding links can easily be exploited to spread viruses and worms, please skip this method altogether.

For the sake of simplicity, here is a step-by-step guide to accomplishing this goal within Gmail. Go to Tools & Contact Manager, then choose Create Contact Group. Enter your name and pick a unique ID. Next, enter the names of people whose details you wish to include in the contact group. Click Save.

All you have left to do now is copy the HTML code generated by Gmail and paste it somewhere public. Then, share the URL via social media sites like Twitter, Facebook, etc., or post it on Craigslist. Whenever someone clicks on the link, he/she will instantly join your group.

Can I send 100 emails at once in Gmail?

Yes! As long as you stay below Gmail's daily allowance, you shouldn't encounter problems. Here are three methods you can employ to send large amounts of email simultaneously.

1. Use templates and BCC fields

First, you can utilize the features provided by Outlook and Hotmail to split your message across multiple recipients. Simply insert columns between paragraphs of text and format them differently. It's important to remember that you must separate each column with either a comma or line break (i.e. --BCC: Otherwise, you might end up breaking the formatting rules or making your email look unprofessional.

2. Send email chains via Google Groups

Second, you can use Google Groups to chain together dozens of emails. Just follow our previous instructions on creating a contact group, except replace the word “group” with “forum”. Afterward, attach the resulting file to an outgoing message. Your recipient(s) will be able to view the entire thread by clicking on the attachment.

3. Forward emails

Finally, you can bypass the aforementioned limitation entirely by asking your friends to forward your emails to groups of their choosing. Of course, you still run the risk of violating Gmail's policy, especially if your forwarded emails contain attachments. But hey, maybe you can convince them to do it anyway.

How many email addresses can you use in one email?

This question has no easy answer. It depends largely on the size of your company, the nature of your job, and the frequency with which you communicate with coworkers.

As far as personal correspondence goes, it seems reasonable that you can safely maintain four active email accounts. Most individuals probably aren't interested in keeping more than that though.

That said, there are plenty of cases where maintaining multiple email accounts is beneficial. For instance, say you work for both a small business owner and a corporate office full of middle managers. If you manage both entities' finances separately, it makes sense to have an accountant monitor transactions coming from the former and a legal team handle matters related to the latter.

On the other hand, if you coordinate schedules and assignments between a dozen employees, it's best to consolidate everything onto a single account. This saves time spent opening numerous tabs and lets you focus on managing your workload better.

We recommend avoiding using more than four email addresses per domain. If you ever happen to fall victim to identity theft, you can rest assured knowing that your stolen login credentials remain useless thanks to strong authentication measures built into modern web browsers.

If you're a regular user of popular web services like Gmail, Facebook, Twitter, Instagram, Spotify, Reddit, Dropbox, etc., it's likely that your account has been targeted by spammers. These scumbags are known for using botnets -- massive networks of computers running automated software programs -- to flood these sites with junk messages and links.

Fortunately, there is an easy way to fight back against this onslaught of unwanted traffic. It’s called “email overloading,” where people use bots (or other tools) to quickly flood their inboxes with hundreds, thousands, even millions of pieces of unsolicited mail all from different domains. The idea behind email overload is simple enough, but how much email can one person handle before becoming overwhelmed with clutter? And what exactly does "overloaded" mean anyway?

The answer depends on who you ask. According to Google’s official support pages, while they don't have any set guidelines regarding sending too many emails, they do suggest users turn off autoresponders when possible so as not to clog up peoples' inboxes. As such, we'll focus our discussion here on whether someone should be able to send 50-100+ emails in a single session without problems. For comparison purposes, let's also consider some basic rules for normal email etiquette.

According to those same Google support pages, most ISPs will cap the maximum amount of incoming email at around 10GB per month. This means that if you were to receive 1 million emails per day via standard delivery methods, you'd only be allowed to see about 998,000 of them. If you tried to open each message individually, it would take you about two years to read everything!

So, what happens if you want to exceed this limit? In order to avoid getting blocked by your ISP, you need to resort to alternative ways of delivering your emails. Some may argue that since you aren't being charged extra money for additional space, why shouldn't you send whatever you want whenever you want? Others say that because of the high likelihood of viruses and malware lurking within these files, the best bet is simply to wait until later. But if you really insist on pressing the issue, then you might try creating multiple Gmail accounts.

But first things first -- if you've got dozens of active Gmail accounts, perhaps you could benefit from consolidating them into a unified inbox instead of having separate ones for every service. We recommend, which lets you manage newsletters, promotional offers, social media alerts and more in just one spot. You can easily delete individual subscriptions or groups of them from the settings page. Just click the unsubscribe button next to any newsletter you no longer wish to receive, and follow the prompts. To create new labels, go to Labels & Filters in Settings.

Now that we know roughly how much email you can expect to receive daily, let's talk about how to actually exceed that limit. There are several approaches you can employ to increase the size of your inbox, but none of them are particularly elegant. One method involves mass forwarding your messages to another address entirely. While this approach works well in theory, it becomes unwieldy very quickly. Not only do you end up flooding your primary mailbox, but you also risk accidentally forwarding something sensitive to the wrong recipient. That said, if you absolutely must forward emails beyond the capacity of your main inbox, check out Mail Forward Pro [No Longer Available]. This tool allows you to specify unlimited recipients and forwards, making it ideal for spreading a deluge of mail across numerous platforms. With proper security precautions taken, however, forwarding emails is safer than ever.

Another option for exceeding the sender quota is to change your outgoing server settings. By default, Gmail uses its own servers to deliver your messages. When you start receiving lots of messages, though, the company recommends switching to Yahoo's SMTP servers to make sure your messages reach their destination as fast as possible. Of course, doing this requires you to switch away from Gmail completely, which isn't always practical. So instead, you can install a third-party client that supports multiple providers, including Sendmail/Postfix and QMail. Or you can configure your own private MTA (Message Transfer Agent). Whichever solution you choose, it won't cost anything extra and won't require any technical expertise.

Finally, if your goal is to overwhelm others with emails rather than yourself, you'll probably find better success going after someone else's personal email address(es) than trying to hit big companies. Most folks have several free email addresses associated with various online accounts. Simply search through LinkedIn profiles, look up phone numbers on Yelp listings, scan Craigslist ads, browse Twitter bios, and dig deeper into other public records. Once you identify several potential targets, send them a few test messages to see if they respond. Then, once you’ve determined that their responses indicate interest, you can proceed with a systematic barrage of messages.

With luck, you now understand how to effectively circumvent inbox limitations imposed by major email providers. Good luck avoiding future spam attacks!

In addition to limiting the total volume of email sent from your account per day, modern systems often impose limits on the number of times a particular domain name appears in the From field of your e-mails. A common example is Hotmail, where the system blocks repeated attempts to send mail from an IP Address outside the country Hotmail was registered in. Such measures are intended to stop hackers from attempting to compromise a given domain’s integrity by overwhelming its administrative staff members with junk mail.  The problem arises when legitimate customers of Hotmail, Gmail et al become victims of phishing scams and other forms of identity theft.

How do I send large numbers in Gmail?

Emailing friends and family: Sending large amounts of email to individuals is generally acceptable provided they’re willing participants and the content doesn’t contain malicious code. However, sending huge volumes of bulk mails to random strangers – especially unrelated parties – raises questions of privacy and ethics. On top of that, if a given party receives a lot of unsolicited commercial advertising, spam filters may block them automatically.

Sending large quantities of emails to mailing lists: Email list operators usually abide by the same rules as everyone else. Spamming mailing lists is illegal.

Sending large quantities of emails to websites: Generally speaking, website administrators prefer not to receive excessive amounts of traffic. If you run a site that attracts large audiences, you may want to consider purchasing a dedicated IP Address or hosting plan specifically designed for handling higher levels of traffic. Otherwise, it’s recommended that you contact the administrator directly and explain your situation. They may allow you to temporarily boost your bandwidth usage, depending upon your circumstances. Note that this strategy is less effective at saturating email servers than a direct attack on personal email addresses.

Using proxy servers: Proxy servers are commonly used by Internet Service Providers to connect clients to certain destinations. Many larger organizations have elaborate systems designed to detect and filter unauthorized access to internal network resources. Even if you bypass these safeguards, you’ll still trigger alarms due to the sheer quantity of packets flowing between your computer and remote servers. Thus, proxies are typically limited to short bursts lasting mere minutes or hours at most. After a period of time, you’d need to repeat the process again to renew the connection.

Forcing emails through VPNs: Using Virtual Private Networks provides similar results to proxy servers, except that they tend to offer greater reliability under heavy loads. Again, this technique is useful primarily for attacking specific entities. Like proxies, VPN solutions are unable to sustain traffic for extended periods. Also, forcing a flow of data through encrypted tunnels can sometimes result in packet loss and performance degradation.

Comparing options: Let’s compare some strategies available for increasing throughput rates:

Directly targeting existing email addresses: Assuming you already have an established relationship with the recipient, this tactic carries minimal risks. Your target will either ignore your request outright or respond politely. Either outcome falls below expectations.

Targeting pre-existing mailing lists: This strategy represents a middle ground between full saturation tactics and brute force attacks. List owners rarely object if you submit small batches of requests at intervals spaced apart. However, if you attempt to bombard them with emails en masse, they may blacklist your IP Address altogether.

Creating temporary mailing lists: If you perform tests involving smaller groups of contacts, you can register a series of dummy email addresses specifically meant for testing. Later, when you come prepared with real email IDs, you can pass them along to interested parties. Since they lack permanent status, these addresses cannot cause long delays.

Setting up proxy servers: Setting up a proxy server allows you to transmit multiple streams of information simultaneously. Unlike VPN technology, proxies provide reliable connectivity regardless of load conditions. Therefore, you can safely maintain continuous connections between your computer and various locations throughout the world indefinitely. Unfortunately, setting up a proxy server takes considerable effort and knowledge. Moreover, unless you operate specialized equipment, you may struggle to overcome bottlenecks caused by upstream routers and firewalls.
