What it really isA budget email newsletter tool for creators, run by the AppSumo team.

Our takeSendFox is worth a look if your list is small and your newsletters are simple.

The $29 Lifetime plan is the headline, but 300,000 total sends go faster as the list grows: 5,000 contacts mailed weekly uses them up in under 14 months. Pro at $19 a month removes branding and adds the VIP sending IP.

Why we rate itLow prices on every tier, with forms, landing pages, automations and Stripe paid newsletters included.

The catchSmall free plan, branding until Pro, and a Lifetime plan with a hard total send cap.
