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.
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.
