Budget pressure: Moosend starts at $9/mo. If that's too steep, MailerLite, Brevo (Sendinblue) offer free tiers. The cheapest option isn't always the best — but neither is overpaying.
Feature mismatch: Moosend's strengths are very affordable and good automation features. If you need something it doesn't do well — no free plan (30-day trial) — one of these alternatives fills that gap.
Scale: What works at 1,000 subscribers may not work at 50,000. Re-evaluate your platform as your list grows — pricing and feature needs change faster than most people plan for.
