Setup SPF (Sender Policy Framework) for your domain for better email deliverability.
The following are some of the SPF records from popular email hosting solutions. You need to add them as a TXT record for your domain.
Google Workspace
v=spf1 include:_spf.google.com ~all
Zoho Mail
v=spf1 mx include:zoho.com ~all
Mailgun
v=spf1 include:mailgun.org ~all
Zendesk
v=spf1 include:mail.zendesk.com ?all
Microsoft 365
v=spf1 include:spf.protection.outlook.com -all
Rackspace
v=spf1 include:emailsrvr.com ~all
Amazon SES
"v=spf1 include:amazonses.com ~all"
GoDaddy
v=spf1 include:secureserver.net –all
Fastmail
v=spf1 include:spf.messagingengine.com ?all
SendGrid
v=spf1 a include:sendgrid.net -all
Mailjet
v=spf1 include:spf.mailjet.com ~all
MailerLite
v=spf1 include:_spf.mlsend.com ~all
AWeber
v=spf1 include:send.aweber.com ~all
If you need to add more than one then you can combine them by adding another in the single entry instead of adding them separately.
Ex – if you need to add Google Workspace and Mailgun, both then you can below.
v=spf1 include:_spf.google.com include:mailgun.org ~all
Once you are done with the implementation, you can use the SPF test to verify the record.
