My followups are getting bounced or deferred by my email provider.

If you suspect your email provider is blocking or deferring messages from FollowUpThen, please contact your email hosting provider or IT department and ask them to whitelist emails coming from FollowUpThen. This can be done as follows:

  • Whitelist email is sent from
  • Whitelist emails coming from the domain
  • Whitelist emails with return-path
  • Whitelist our IP addresses. We use Amazon to send email. The IPs for this service can be easily found by running:  dig TXT +short| grep ‘v=spf1’
