In this help center article we go over how to create a custom SPF Record (TXT).
- Admin Access to your organization's Domain Host
Why & What
If you use multiple applications to send email from your domain (via routing, relaying, etc), then you will need to make sure your TXT record includes those senders. Otherwise some recipient security will block and/or bounce back your emails.
So what is a TXT record, specifically a SPF? SPF is a Sender Policy Framework that acts as a caller id of sorts to help validate that your email was allowed to be sent from that particular application. For example, our current SPF record includes Google and Paubox because our emails are coming from those two servers. If we did not include Google and/or Paubox, then a lot of our outbound emails would NOT arrive.
Below is the TXT record for a domain using G Suite and Paubox. Highlighted in blue are the servers that are identified to send email from this domain.
Here is an example of a domain that might be using multiple applications like Sendgrid and Mail Chimp. We have highlighted each server that is currently sending email from that domain.
Pro-Tip: A SPF record is limited to 10 includes. If you have to go over 10, please contact us and we can help you troubleshoot the best solution.
To create a custom record, as long as you do not have more than 10 records already, all you need to add is edit your existing record and insert Paubox's spf include. We have provided directions below.
- Login to your Domain Host
- Find Manage DNS
- Identify your TXT record with SPF
- Select Edit
- Copy and paste Paubox SPF into the existing SPF at the end. Be careful not to place any extra spaces as this can cause an error resulting in bounce back emails.
- Click Save
