Campaigns, automations, and transactional email. All from your own domain.

Your own sending domain

DKIM, SPF and DMARC records are generated for you, then verified automatically.

Unlimited contacts

Store, tag and segment as many subscribers as you need. Pricing follows volume, not list size.

Opens, clicks and bounces

Every recipient gets a tracked status, and bounce or complaint feedback updates their record.

API, webhooks and MCP

Send from your product, subscribe to delivery events, or let an AI agent run the workspace.

What you can send

Everything your customers receive, in one place

Three ways to send, one audience and one history. You do not have to stitch a marketing tool, an automation tool and an email API together.

Campaigns

Write once and send to a segment of your audience.

  • Drag-and-drop builder with reusable blocks
  • Email designs you can duplicate and reuse
  • Send immediately or schedule for later

Automations

Sequences that react to what a customer does.

  • Trigger on events, tags or attribute changes
  • Wait steps, conditions and branching paths
  • Enrolment and per-step reporting

Transactional email

Product email triggered from your own application.

  • Send through the REST API with an API key
  • Categorised templates for account, orders and alerts
  • Delivery history for every message you send
Browse every feature

See the platform

One workspace, from audience to delivery

No separate tools for newsletters, lifecycle journeys and product notifications — and no guessing what happened after you hit send.

  1. 01

    One dashboard for every message type

    Campaigns, sequences, transactional sends, subscribers, sending domains and analytics share the same workspace.

  2. 02

    Audience health you can act on

    See active, unsubscribed, bounced and complaining contacts, plus how many active subscribers are already inside an automation.

  3. 03

    A real status for every send

    Each email moves through queued, sent, delivered, opened, clicked, bounced or complaint — per recipient, not per campaign.

How it works

From signup to first send in four steps

There is no migration project and nothing to install. Most teams are sending their first campaign the same day they add their domain.

  1. 01

    Verify your sending domain

    Add a domain you own and drop the generated DKIM, SPF and DMARC records into your DNS provider. MailTier re-checks them until they resolve.

  2. 02

    Import your audience

    Upload a CSV or push contacts in through the API, then tag them and build segments from attributes or subscriber status.

  3. 03

    Build the email

    Start from a template or a blank canvas, or describe what you want and let AI draft the blocks for you.

  4. 04

    Send, automate and measure

    Launch a campaign, switch on a sequence, and follow opens, clicks and bounces for every recipient.

Deliverability

An email platform is only as good as the inbox it reaches

MailTier sends through your own authenticated domain, keeps your DNS records honest, and cleans the audience when a mailbox rejects or reports you.

How deliverability works
  • Every sending domain gets its own SPF, DKIM and DMARC records, checked against public resolvers until they resolve.
  • Bounce and complaint notifications update the subscriber record automatically, so bad addresses stop receiving mail.
  • Click-tracking links are HMAC signed, so your redirects cannot be hijacked or used as an open redirect.
  • Unsubscribe links and hosted unsubscribe pages are built into every message.

For developers

Wire it into your product, not around it

Product email, delivery events and the whole workspace are reachable from your code — or from an AI agent.

  • REST API

    Manage contacts, campaigns, sequences and transactional sends over HTTPS using workspace API keys.

  • Signed webhooks

    Subscribe to email.sent, delivered, opened, clicked, bounced, complaint and subscriber events.

  • MCP server and in-app AI

    Expose the workspace to AI agents over MCP, and draft emails, pages or forms from your brand context.

Pricing

Pay for the emails you send. Nothing else.

Most platforms charge you twice: once for the contacts you store, and again for the emails you send. MailTier only charges for volume.

  • Start free with 2,500 emails a month
  • Unlimited contacts, lists and segments
  • Unlimited team members and sending domains
  • No daily sending limit
  • Every feature included — you only pay for volume

Questions

The things people ask before they switch

Still deciding? A short call is usually faster than reading release notes.

Do I need my own domain to send?

Yes. You send from a domain you own, which is what keeps your reputation yours. MailTier generates the DKIM, SPF and DMARC records and keeps checking them until your DNS provider resolves them.

How does pricing work?

You pay for emails sent, not for contacts. The free plan covers 2,500 emails a month, and every plan includes unlimited contacts, unlimited sending domains and every feature.

Can I send transactional email from my product?

Yes. Create an API key, add a template, and send through the REST API. Transactional templates are grouped by category — authentication, account, orders and notifications — and every send is logged.

How do I know mail is being delivered?

Each recipient carries a status: queued, sent, delivered, opened, clicked, bounced or complaint. Opens and clicks are tracked per recipient, and delivery events can be forwarded to your own endpoint by webhook.

What happens to bounced or complaining contacts?

Bounce and complaint notifications are processed automatically and the subscriber is marked so they stop receiving future sends. You can review and clean the audience at any time.

Which tools does MailTier connect to?

Stripe, Shopify, WooCommerce, Paddle, Lemon Squeezy, Clerk, PostHog, Supabase, GitHub, Zapier, plus inbound and outbound webhooks and the REST API for anything else.

Start sending in minutes, not weeks.

Create a workspace, verify the domain you already own, import your list, and send your first campaign today — with deliverability you can see.
