Is it possible to merge these 2 SPF records? – CPanel

I’m attempting to set up mailerlite with authentication and they provided me with this SPF record to add to my domain.

I added the record but now I have 2 and the authenticator says that I can only have 1 SPF record and that I need to merge the 2 records into 1 for both to work.

Is it possible to merge these 2 SPF records into 1 spf record?

cPanel SPF record:

v=spf1 ip4:162.0.229.20 ip4:162.0.229.21 include:spf.web-hosting.com +a +mx +ip4:198.54.114.47 +ip4:198.54.114.173 ~all

Mailerlite SPF record:

v=spf1 include:_spf.mlsend.com ip4:162.0.229.20 ip4:162.0.229.21 include:spf.web-hosting.com +a +mx +ip4:198.54.114.47 +ip4:198.54.114.173 ~all

    The second one seems to include every info that’s present in the first one, so why not just use it and not add the second one?

    As others have said, these are essentially the same, but you can optimise them a little.

    • Put literal ip4 and ip6 mechanisms first as they can be resolved without DNS lookups
    • You don’t need to use + prefixes because that’s the default action
    • Put a before mx as it likely involves fewer lookups
    • Put includes last for the same reason

    Resulting in:

    v=spf1 ip4:198.54.114.47 ip4:198.54.114.173 ip4:162.0.229.20 ip4:162.0.229.21 a mx include:_spf.mlsend.com include:spf.web-hosting.com ~all
