What should I do if I get a bounce rate warning?

A warning from your provider (for example, Mailchimp, Amazon SES or Mailrelay) usually means a high number of undelivered emails, also known as bounces. Email sending services monitor email performance to keep the service reliable for all users.

There are several things you can do to reduce bounces and improve your sender reputation, including verifying your email lists regularly and following email sending best practices. To verify your list now, sign up here.
