Features

Everything in one place. Not seven tabs and a Zap.

We don't ship the parts of the lifecycle stack you don't need. We ship them all, with the level of polish you expect from your favourite product tool.

Campaigns

A broadcast editor designers stop complaining about.

The Mailapp editor is built on a drag-and-drop block model with a code escape hatch — not the other way around. Designers get fine type control, devs get a clean DOM, and the HTML output renders in every client we test against.

Send to a list, a segment, or a query. Schedule, drip, or send-time optimise. Use merge variables that map to a real schema, not strings glued together at request time.

Block + code editor
Drop in code wherever, no clipboard surgery. Custom HTML blocks live alongside design blocks.
Send-time optimisation
Each contact is sent at their best time of day, learned from past opens — without a separate plan.
Liquid templating
Merge with conditionals, loops, and fallbacks. Auto-completion against your live schema.
Cross-client previews
Litmus-style preview built in — 30+ clients, dark mode, low-vision contrast checks.
Multi-language sends
One campaign, many locales, switched by trait. Translate with the AI assistant, your TM, or both.
Approvals and reviews
Mandatory reviewers, change requests, version compare. SOX-friendly audit trail.
Automations

A real graph, not a wall of cards.

Lifecycle journeys deserve a real builder. Mailapp's automation canvas is a directed graph — nodes for sends, waits, branches, A/Bs, goals, exits — with version history, live observability, and instant preview against any contact.

Every change is a commit. Diff, revert, and protect branches with required approvers.
Goals and exits
End the journey on conversion, not on a calendar. Re-enter rules with cooldowns.
Audience

The CDP you'd build if you had a year.

A real event-based customer data platform. Send events from your product, sync traits from your CRM and warehouse, compute properties from raw behaviour. Every campaign and automation references segments by name — they update the moment a user does, not the moment you click "refresh list".

Inbox

Replies are first-class citizens.

Most ESPs treat replies like a leaky pipe. Mailapp ships a real shared inbox with assignment, SLAs, macros, and AI-assisted responses that pull live context from the contact profile.

AI assistant

An operator, not a chatbox.

The Mailapp assistant is built to do work — not narrate it. Ask for a segment, get a segment. Ask for a series, get a draft with version diff. Ask why open rate dropped, get a root-cause with a fix you can approve in one click.

AI assistant
Acting on your data
Find power users at risk of churn and draft a re-engagement.
Reviewed 24,812 contacts · 7 segments
412 power users haven't opened in 60+ days. I built a segment, drafted a 3-email re-engagement automation, and queued an A/B on subject line.

Trained on your past campaigns. Pin examples for the AI to mirror. Style guides stick.
Reports on demand
Plain-English questions, structured answers, with the SQL or builder steps revealed.
Audit log
Every AI action is logged with input, output, and approver. Comply with anything.
Local model option

MCP-native
Plug Mailapp into Claude, Cursor, or your own agent via MCP. Same primitives, anywhere.
Templates

A template editor designers and devs both enjoy.

The editor renders real MJML under the hood, exposing both a block UI and a code surface. Tokens drive type, colour, and spacing — change a brand variable and every template updates.

Design tokens
Brand colours, type scale, spacing. Updates propagate to every template.
Re-usable layouts
Compose templates from sections. Lock content, unlock styling, or vice versa.
Real HTML output
Renders cleanly in Outlook for Windows. We test on it weekly.
Dark mode aware
Per-block dark variants, auto-generated fallbacks. Test in both modes.
Code blocks
Drop in raw HTML or MJML anywhere. Auto-formatted and validated.
Library and history
Every template versioned. Restore any prior version. Compare diffs visually.
Forms

Forms that don't redirect or break your design.

Inline, popup, modal, full-screen, or embedded — all without a redirect, all behaviour-aware, all themable to match your site exactly.

Targeting rules
Show on URL, on exit, on scroll, after time, on identified vs anonymous.
Multi-step
Wizard flows with logic jumps, file uploads, calendar pickers.
Themable
Inherit your site's CSS, or design from scratch with our block editor.
Spam protection
Invisible challenges plus rate limiting. Honey-pots, RPM caps.
Consent + tracking
Per-form consent banners. Capture UTM, referrer, and source on submit.
Submissions inbox
Filter, route, tag and reply to submissions from the same shared inbox.
Deliverability

A boring deliverability story is the best deliverability story.

We've spent five years building shared and dedicated pools with reputation that holds across the big providers. We auto-generate SPF, DKIM, DMARC, BIMI and tracking records — and we'll co-pilot warm-up of a dedicated IP if you bring one.

Auto-DNS for every domain
We propose the records, validate them, and tell you when something drifts.
Reputation monitoring
Per-provider scoring across Gmail, Yahoo, Outlook, Apple. Alerts when scores dip.
Seed lists + content scoring
Pre-send simulations against Spam Assassin and provider-specific filters.
Warm-up automation
Bring an IP, get a guided warm-up over 4 weeks with live reputation reads.
Bounce + complaint loops
We process FBLs from Gmail, Yahoo, Outlook, AOL, and more. Bounce metadata is structured.
Postmaster integrations
Pull from Google Postmaster Tools and Yahoo Sender Hub into the same dashboard.
