Email infrastructure, done properly
MailGrid gives organisations the infrastructure to run branded email at scale: provisioning domains and mailboxes, wiring authentication, and delivering mail that reaches the inbox.
Make branded email infrastructure something anyone can run
Standing up authenticated, deliverable, two-way email used to mean operating mail servers, wrangling DNS, and fighting spam filters. We turn that into a platform, so teams ship branded mailboxes on their own domains in minutes, not months.
Principles behind the platform
Own your domains
Every tenant runs email on their own branded domains with white-label DNS, SPF, DKIM, and DMARC.
Real infrastructure
Backed by Stalwart for IMAP/SMTP and Amazon SES for delivery. Not a thin wrapper over a shared inbox.
Deliverability first
Authentication, reputation monitoring, and classification keep legitimate mail in the inbox.
Multi-tenant by design
Strict isolation between tenants, with per-mailbox contacts, templates, and controls.
Send and receive
Full two-way email: send via SES, receive over MX, sync with any IMAP client.
Cross-client
Works with Gmail, Outlook, Apple Mail, and Thunderbird alongside the built-in webmail.
