## System Resources

As with all email sending providers, Account Engagement can send a fixed number of emails per hour. In general, the amount of time it takes to send an email is directly related to the number of recipients on the distribution list. Emails with more than 1 MB of text content can take more time to process and send. Images and variable tags don’t affect performance.

## Best Practices for Email Marketing

Using email marketing wisely helps deliver great performance, even when your distribution lists have many prospects.

Choose the Best Order for Email Sends

Account Engagement sends emails in the order they’re scheduled. Collaborate with your team and decide the best order for scheduling the emails, including A/B testing emails and campaign emails. Consider that automation rules and engagement programs can also send emails.

Consider Smaller Distribution Lists

If you can, create and use smaller distribution lists. These emails are sent more quickly.

Schedule Large Email Sends Early

It takes time to prepare and send an email, and the amount of time it takes is related to the number of recipients. We recommend that you schedule large email sends a little earlier than you want them to be delivered. For example, let's say that you have a distribution list of with more than ten thousand recipients. We recommend that you set up the email send a couple of hours before the scheduled send time.
