SPF (Sender Policy Framework) is an email authentication mechanism that allows a domain’s administrator to specify which IP addresses are allowed to send an email on behalf of the domain, thus preventing others from forging their identity. SPF lets you protect the senders of your email from spam complaints. It helps keep your reputation intact and maximizes deliverability.
In order to specify Elastic Email as an authorized email sending source for your domain, you need to add an SPF record for Elastic Email.
Adding an SPF Record for Elastic Email
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Elastic Email will have the following syntax:
yourdomain.com TXT v=spf1 include:_spf.elasticemail.com -all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Elastic Email. If you do have an existing SPF record in your DNS, you need to modify it to include Elastic Email, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include_spf.elasticemail.com: -all
Wait for 72 hours to allow your DNS to process the changes
