Starting Feb 2024, gmail will require senders who are sending more than 5000 emails a day to setup SPF authentication. See updated gmail sending requirements in Feb 2024. We recommend all email senders to add the following SPF record for OnVoard.
Go to your DNS provider and for your sending domain, add the following TXT record for SPF.
v=spf1 include:spf.onvoard.com ~all
What if you already have an existing TXT record for SPF?
If you already have an existing TXT record for SPF, you have merge the SPF entries into a single TXT record. Do not add multiple TXT records for SPF. It will cause SPF to check to fail.
Don't do this
Don't add 2 TXT records for SPF
|v=spf1 include:_spf.google.com -all
|v=spf1 include:spf.onvoard.com -all
Merge all SPF entries into a single TXT record
