How to Troubleshoot Email Delivery Problems

If there is an issue with email delivery to your recipients, the information below can help you to troubleshoot them.


We use SendGrid for email delivery, SendGrid sets the return path on any email that's delivered to your recipients to match our domain. This means that DKIM and SPF setup shouldn't be necessary and most mail clients will be transparent about the sender and include something like 'via Accredible' in the From field.
