MailInApp vs Brevo
Brevo (formerly Sendinblue) is well regarded for pricing on sends rather than stored contacts, and for a genuinely generous free tier. MailInApp adopted the same send-based pricing philosophy — and adds a layer of native in-email interactivity Brevo's own template builder doesn't have.
The real difference
Both platforms agree that charging for contacts you're not emailing is the wrong model. Where they diverge: Brevo's emails, however well designed, are still static HTML with links out. A MailInApp poll, quiz, or RSVP records a response the instant a recipient taps it, inside the email, with a fallback path for clients that can't render it — no separate landing page required to capture that first interaction.

Why teams pick MailInApp
- Interactive blocks (polls, quizzes, RSVPs, product checkout) with no external landing page needed to capture the response
- A journey's send step can be a real interactive email, not just a static template
- The same send-based, contacts-are-free pricing philosophy Brevo is known for
Where Brevo still leads
- Brevo's free tier currently allows more stored contacts and a higher free monthly send volume
- Brevo bundles SMS/WhatsApp and a broader CRM feature set MailInApp deliberately doesn't build
Frequently asked questions
Does MailInApp also do SMS or WhatsApp?
No — those channels are deliberately out of scope. MailInApp focuses on making the email itself richer rather than adding parallel channels.
See what native sending covers →Why is Brevo's free tier bigger?
Brevo has years of scale behind its free-tier economics. MailInApp's free tier is intentionally competitive with the category rather than the single largest — see the pricing page for the exact current numbers on both.
