ImprovMX SMTP is a robust mail sending feature available on our Premium and Business plans.

If you anticipate using ImprovMX SMTP for bulk mailing or mailing lists, it's worth keeping in mind that is not designed for this kind of usage. If you're on the Premium plan and are sending over 200 emails per day with ImprovMX SMTP, it's recommended that you do one of two things:

  1. Upgrade to a business-tier to better accommodate the usage (2000 sent mails per day - see full details of limits here). Or...

  2. Utilize a service designed for bulk and/or large sending.

We hope to offer a more robust sending solution in the future, but don't quite have a timeline on development just yet.
