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

Zoho Mail

Mailgun

Zendesk

Microsoft 365

Rackspace

GoDaddy

Fastmail

SendGrid

Mailjet

MailerLite

AWeber

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. Once you are done with the implementation, you can use the SPF test to verify the record.
