💡 What most people get wrong

From real user experiences:

“Mailchimp pricing increases quickly as your list grows.” Reddit

That’s the biggest trap—contact-based pricing looks cheap early, then jumps hard at 5k–10k subscribers.

🏆 Bottom line

• Tight budget + scaling fast: → go with Brevo

• Beginner + simple needs: → MailerLite

• Content/newsletter focused: → ConvertKit

• All-in-one + big ecosystem: → Mailchimp (if budget allows)

If you want, tell me:

• your niche (e.g. ecommerce, newsletter, SaaS)

• list size (now + goal)

• how often you send emails

…and I’ll recommend the cheapest option specifically for your situation.

If you’re focused on affordability + scaling your list, the key is understanding how pricing works:

• Per-contact pricing → gets expensive as your list grows

• Per-email pricing → better for large lists with moderate sending

• Flat-rate / unlimited → predictable cost long-term
