Our recommended link
Every time someone books a consulting call, joins the Lab, or fills out a form - they get an email. That email comes from Resend.
Inside GHL, transactional emails were bundled into the $1,100/month platform. With Resend, I pay per send. For my volume, that is under $5/month. Same deliverability. Better API. No lock-in.
How Claude Uses It
Claude Code has access to the Resend API credentials. When I need a new email workflow, I describe it to Claude - trigger, recipient logic, content - and Claude writes the script and tests it. I review, approve, and it runs. No email builder. No workflow drag-and-drop. Just a script that does exactly what I need.
