What Are Email Recipient Limits?
When you send email to multiple recipients, there are certain standard precautionary limits that you need to be aware of. Email recipient limits apply to messages sent from your address and entails the calculation of the total number of email addresses that you are sending the email to. This includes not just the “To” email recipient/s but the “CC” (Carbon Copy) email addresses, as well as “BCC” (Blind Carbon Copy) email recipients.
Exceeding this threshold may result in them being marked as spam and impact their deliverability. The email recipient limit for a message depends on a range of factors including your email provider, type of account, and email client itself e.g., Microsoft Outlook, Gmail, Apple Mail.
Here are some guidelines to follow:
Email Recipient Limits – 15-20 people per mail is the typical number of email addresses set to receive a single email.
Mail Size – The size of emails and attachments can impact delivery. Some email providers have message size limits for email attachments (in total) that can be received. Large emails may trigger a recipient server’s spam filters.
When sending out any type of commercial electronic mail message, it is more prudent to consider utilizing 3rd party applications that have been specifically designed for multiple, subscribed email recipients.
Sending one email to multiple recipients, known as bulk email, can help save time as opposed to sending it individually. However, sending emails to a high number of recipients can result them not receiving your mail due to the limits set on the amount of email recipients that one is able to send it to. Knowing the recipient limit for email messages, can help avoid triggering spam filters and delivery issues. In this article, we will explore these and provide practical guidance on achieving optimal results.
Best Practices for Sending Bulk Emails
By following best practices when sending email to multiple recipients you can avoid spam filters and increase the chances of your message being delivered to its intended audience.
Some best practices to follow include:
Keep It Below 15 Recipients – This helps to not trigger spam filters and boosts deliverability. It may also help with open rates as people may not see it as a generic bulk mail.
Do Not BCC – Using the BCC field to hide the email addresses of other recipients may result in it being marked as spam, if there are too many.
Group Your Recipients – Avoid sending emails to large groups of people who don’t know each other or outside your network.
Utilize Bulk Email Tools – Use an email service specifically designed to send bulk emails if you are doing cold email outreach.
Keep Attachments Small – Sending emails with large attachments may result in them not being sent due to file size limits.
Why Email Limits are Put in Place
To help prevent spam and keep accounts safe, email providers may limit the number of emails that you can send per day, and the number of people you can send a single email to.
Spammers sometimes use single accounts directly to send vast numbers of emails to multiple recipients. Putting limits on how many one single account can send in any set period of time, makes it more difficult for them to do so.
By sending emails to multiple recipients in a short period, could result in your email address or domain being black-listed by Internet Service Providers (ISP). If your email address gets blocked, your emails could be filtered directly to recipients’ spam folders, or blocked completely.
Email Spam Filters
Email spam filters are designed to identify and block unsolicited, or malware-infected messages. These filters analyze incoming mail to detect potential junk mail by scanning for spam-like features. The filters then calculate the probability of the message being spam and either sends them to a spam folder or blocks them.

Bandwidth Allowance and Emails
Your hosting plan’s monthly bandwidth allowance includes sending and receiving email. Bandwidth is used when you send or receive emails as that data is uploaded to and stored on your hosting server. This means that the size of your emails and their attachments, are counted towards your monthly bandwidth usage.
If your allocation is exceeded, your email service may become unavailable, in which case you may need to upgrade your hosting plan.
Note: Sending to multiple email recipients on the same domain’s server, does not impact bandwidth as it is usually considered as a single email.
It’s important to be aware of the email limits to avoid any issues with sending out email communications. By following best practices, you can help ensure that your emails are not marked as spam and delivered successfully.
