Yes, it is generally a good idea to add SpamHero to your SPF record to help in a few scenarios:
- Inbound mail from your domain that goes through SpamHero will pass SPF checks, improving deliverability to your mail host.
- Outbound mail from your domain will have much higher delivery rates when you have an SPF record.
- If you are a reseller with a custom domain, it will improve the deliverability of quarantine reports to your users.
