Send emails as your clients
Which inbox would your client's customer trust?
Add a client in the dashboard, pick a template, and their customers start getting emails from the right name. No domain to buy. No DNS to touch. Every client gets isolated reputation automatically.
Under the hood
Every piece runs automatically the moment you add your first client. No configuration required.
RSA-2048 key pair per client. Generated in 180ms on first send, published to DNS, rotated every 90 days. No two clients share a key.
Each client sends from their own subdomain on mailmont.com. Return-path aligns. DMARC is strict. Gmail, Microsoft, Yahoo see each client as independent.
New clients start at 50/day, ramp automatically. High opens accelerate. Low engagement slows. Fully automatic.
Proven, warming, probation, quarantine. Bounce spike = auto-move to probation. Other clients stay on clean IPs.
Gmail Postmaster, Microsoft SNDS, Yahoo CFL. Per-client data in minutes. Cross 0.3% = throttled before the next batch.
Hard, soft, role-address — classified separately. Above 5% hard bounce = auto-throttle. All data in your dashboard and via webhooks.
6 of 23 systems. You interact with one: the dashboard. Or the API, if you'd rather automate.
How it works
Type a name. "Bob's Barbershop." We auto-create their subdomain (bobs-barbershop@mailmont.com), generate DKIM keys, and start warm-up. Takes 180ms. You see it appear in your client list.
Use our SDK, SMTP credentials, or webhook integration. Most frameworks — Next.js, Nuxt, Rails, Laravel — have a plugin or just need an API key in your env. Pass the client name with each send.
The end customer sees "Bob's Barbershop" in their inbox. Reply-to goes to Bob's real email. If Bob's bounce rate spikes, he gets auto-throttled. Everyone else keeps sending. You get a webhook.
Prefer code? Full REST API and SDKs for Node, Python, Go, and Ruby. Create clients, send emails, and pull analytics programmatically. Let your AI agents handle it, or build your own integration. See the API docs →
Used by real businesses
Roofing contractors use RoofClose to send estimates, confirmations, and review requests to homeowners. Every email now arrives from the contractor's name. A homeowner sees "Acme Roofing," opens the estimate, books the job.
Gato builds plugins that extend ecommerce stores — post-sale follow-ups, review requests, upsell sequences. Those emails come from the store, not from Gato. The merchant's brand stays front and center. Gato stays invisible.
Pricing
You pay for clients and emails. Nothing when you're setting up.
Card on file required. Keeps spammers out and deliverability high for every client.
