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 AMP →Will 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 works →Can 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.
