Setting up SPF-records for the sender address

To improve deliverability, you need to tell the world that our IP-addresses used for sending e-mail in your name are authorized to do that.

SPF (Sender Policy Framework) is a method used to protect a domain from being used by unauthorized senders (e.g. spammers).

When we send an email with a from-address ending in your domain your SPF-records need to show that our servers are authorized to do that. This allows spam-filters to rely on that the email has really been sent from you. This increases the chance of your email not ending up in the recipient’s junk-mail.

If your company already has an SPF-record for your domain (i.e. the domain you’re using as reply-to in your emails) you simply add include:_spf.ungapped.com before the parameter ~all in your existing SPF-record.

If your company doesn’t have an SPF-record then add a TXT-record in your DNS with the value: v=spf1 include:_spf.ungapped.com ~all

Do not add more than one SPF-record for your domain. If your already have one like:

“v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com ~all”

all you need to do is add the Ungapped domain * just before ~all i.e.:

v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.cominclude:_spf.ungapped.com ~all

NOTE: In case you reach the limit of SPF-records included, maybe you need to include the unique IP address you get assigned by Ungapped.
