What are the limits on email that I send from my site?

Updated on March 31st, 2021

Flywheel uses a third-party service called SendGrid to send emails that come from your website. Because SendGrid specializes in email sending, messages have a much higher chance of being delivered and not ending up in someone’s spam folder.

Flywheel imposes daily email limits to ensure that sites aren’t sending out massive spam campaigns, but are still enough to support site functions such as password resets and form submissions. Keep in mind, in order to prevent abuse of this limit we do not publish the exact amount.


We do not recommend using WordPress to send out newsletters and mass mailings. Instead, we recommend third-party services like Mailchimp or Campaign Monitor, which are available for free or low cost.

Email limits

The limits on emails sent from your website vary based on your plan. You can chat with our sales team to discuss your limits or create a customized plan that works best for you!

If you expect a spike in email or anticipate going over your limit, be sure to contact Flywheel Support as soon as you have those detials. We’ll be happy to work with you to make sure things go smoothly.

What to do if your email is disabled

As part of our anti-spam security measures, a highly unusual spike in emails in a short period of time may trigger a temporary shutdown on email sending from the site.

If your site’s mail is disabled for this reason, limits reset every 24 hours at midnight (UTC) and your mail function will automatically be re-enabled at that time. If you need mail re-enabled more quickly, please reach out to support.


As part of our relentless campaign against spam, we block the sending of email that has been passed through the PHP eval() function. That function is already strongly discouraged in official PHP documentation due to its security risks, so it’s rarely used by legitimate themes, plugins and code.


For sites running on the Flywheel Cloud Platform, Flywheel will notify the site owner via email when the limit is exceeded.

If you do hit the limit consistently, we will reach out and recommend solutions for you – such as switching to Mailchimp or Sendgrid, or selecting a larger Flywheel plan.

Still need help?

As always, if you have any questions, don’t hesitate to contact Flywheel Support.
