Fundraising email authentication

17 Jun 2026 · SHIPPED · integration · The Contentment Foundation

Authenticated a new fundraising sender domain without disturbing the email infrastructure already in production.

Problem

A fundraising platform needed its own authenticated sending domain. The organisation already had live DKIM on the root domain and mail flowing through several providers, so a careless DNS change would have silently started sending donor mail to spam.

Intervention

Designed and applied the DNS and authentication records on Vercel DNS, preserving the existing SendGrid root-domain DKIM and the surrounding Mailgun and Google Workspace configuration.

Result

• Keela and Raisely sending authenticated on their own domain
• Existing SendGrid root-domain DKIM left intact
• No production email outage during the change
