mailgun

Mailgun matters only if the evidence supports a paid workflow around protecting form submissions and lead routing, not a list of isolated fixes. The current commercial thesis is: Businesses lose leads when forms, spam controls, email delivery, or CRM handoffs fail. The entry wedge is to verify lead capture end to end and show where submissions, notifications, or integrations break.
