Use cases

Get Lifetime LicenseMost SaaS companies run password resets on Postmark and marketing on Mailchimp — two budgets, two logins, two failure modes. MailFleet unifies campaign operations on the infrastructure you already operate, especially when product marketing and platform teams share responsibility for delivery.
Onboarding drips, trial expiration reminders, and upgrade campaigns do not require surrendering list data to another cloud. MailFleet manages sends and logs; your CRM or product database remains source of truth for segments.
