Email Sending Limits of Email Service Providers

Updated October 2019

When dealing with big marketing campaigns, many things can go wrong – personalization problems, obsolete lists, numerous follow-ups, and so on. These can all be dealt with with the help of numerous affordable tools and platforms. But when it comes to the sending part of your campaign, you don’t need a tool, you need to know the email sending limits of email service providers to choose the right one.

If you want to compare email providers, jump to the table of email service providers or choose one below:

Why is knowing the email sending limits of your provider important? Because otherwise your email campaign is at risk of not getting delivered and your account may be blocked.

To give you the most accurate comparison of email providers, I have to present the full picture. The table below compares email providers on the following issues: pricing, attachment size limits, recipients/messages per hour limits, and daily email limits.

  1. Pricing. Depending on your budget and campaign size, you might need a free or a paid provider. We will provide information on both options. As a rule, most providers offer a free trial for anywhere between a week and a month.
  2. Attachment size limit. If your email campaign involves attachments, make sure they fit the attachment size limits of your provider. Every ESP differs in this parameter, for example, the AOL email attachment size limit is 25MB and iCloud email attachment limit is 20 MB, while you can send up to 150 MB through 1&1.
  3. Recipients/messages per hour limit. The key characteristic. Every provider sets its own limits, the breaking of which can lead to a temporary ban. Choose your provider depending on the size of your campaign.
  4. Daily email limit. The amount of email that can be sent in a day without getting banned.

If you break the provider’s limits, you will get temporarily banned, meaning your campaign will be paused. We will not be comparing the ban length: usually, the ban lasts only 1-24 hours.

The table is based on the information provided by the providers through their websites or support teams.

All the mentioned email sending limits of ESPs are precautions used to prevent spam-sending and let the provider support all of their users at all times.

The deliverability of your emails depends not only on their content but also the volume of emails sent. Pay attention to email frequency, the amount of sent messages, and stick to the email attachments limitations. Good luck!
