MailInApp vs Mailmodo
Mailmodo is the other platform built specifically for interactive email — carts, forms and surveys recipients complete without leaving their inbox. The real difference is what happens in the roughly 73% of opens, Apple Mail alone accounting for nearly two-thirds, that AMP for email can never reach.
The real difference
Mailmodo's interactivity is AMP-only. It works well in the Gmail app and web client that support AMP, but falls back to a plain, static email everywhere else — Apple Mail, Outlook desktop, and any client without AMP allowlisting. MailInApp takes a different approach: kinetic HTML and CSS, using `:checked` state machines and conditional Outlook markup, with link-first interactions as a universal floor that needs no allowlist approval from Google to start working.
Feature by feature
| Feature | MailInApp | Mailmodo |
|---|---|---|
| Interactivity mechanism | Kinetic HTML/CSS, no AMP dependency | AMP for email |
| Requires Google AMP sender allowlisting | No | Yes |
| Fallback in non-supporting clients | Three-tier degrade (interactive → static links → plain) | Plain static email |
| Entry price | Free, interactive blocks on every tier | No self-serve free tier; interactive-email tools in this category start around $149/mo |
| Own-domain native sending | Included on every tier | Available on paid tiers |
| Automation journeys with interactive sends | Yes — a journey's send step is a real interactive project | Journeys send AMP-gated interactivity, same fallback caveat as any AMP send |
Why teams pick MailInApp
- No AMP allowlisting process to start using interactive blocks
- A visible fallback tier for every client, not just a plain-text afterthought
- Every interactive block available from the free plan, not gated to a $149+/mo floor
Where Mailmodo still leads
- Mailmodo has a longer track record specifically in the AMP-for-email space and deep integrations built around it
- Where AMP is fully supported (the Gmail app, chiefly), an AMP experience can do a few things — like a live, server-rendered cart total — kinetic CSS can't replicate exactly
Frequently asked questions
Does MailInApp support AMP for email too?
No. MailInApp deliberately builds interactivity with kinetic HTML/CSS instead, specifically so it doesn't depend on Google's AMP allowlisting process or the narrower set of clients that support AMP.
Why MailInApp doesn't use AMPWill my emails look broken in Apple Mail or Outlook?
No — every interactive block ships with static fallback tiers designed for exactly those clients, so a poll or survey still looks intentional and works via link-first interactions even where the richest tier can't render.
How the fallback engine worksCan I migrate templates from Mailmodo?
There's no automated importer today. Since MailInApp's blocks are built with plain HTML/CSS rather than AMP markup, recreating a design in the studio is generally faster than adapting AMP source.
