What is TrekMail?

TrekMail is a specialized email hosting platform designed for developers, agencies, and businesses who need full control over their deliverability. Unlike generic email hosts, TrekMail separates the mailbox (where you read mail) from the sending engine (how mail gets delivered), giving you the flexibility to send via our managed high-reputation network or your own SMTP provider (like Amazon SES or SendGrid).

Who this is for

• Agencies & SaaS Founders who need reliable email for multiple domains. Resellers can also rebrand the dashboard and webmail under their own domain via White Label Lite.
• Developers who want to bring their own SMTP (BYO SMTP) for unlimited sending control.
• Businesses migrating from cPanel or legacy hosts who need modern deliverability features.

What you’ll achieve

• Host email for unlimited domains on a single account.
• Separate your "reading" experience from your "sending" reputation.
• Access email via a modern webmail interface or your favorite app (Outlook, Apple Mail).
• Store the files that travel with your email — invoices, contracts, deliverables — in built-in TrekMail Drive.
• Monitor DNS health with real-time alerts when records break.

How TrekMail works

1. The Mailbox Layer

You create mailboxes (e.g., you@yourdomain.com) just like any other provider. We handle the storage, spam filtering, and IMAP connections. You can read your mail in our webmail or connect any standard email client.

Automatic Compression: All emails are automatically compressed using gzip, giving you ~30% more effective storage from your quota. This is completely transparent—your emails work exactly the same in any client.

2. The Sending Layer

This is where TrekMail shines. You choose how your email leaves our servers:

• Managed TrekMail SMTP: We handle the IP reputation and warm-up for you (available on Paid plans).
• Bring Your Own (BYO) SMTP: You connect an external provider like AWS SES, Mailgun, or SendGrid. We route your outgoing mail through them, bypassing our limits entirely. This is mandatory on the Nano plan and optional on all others.

3. The File Storage Layer

TrekMail Drive is built-in file storage that lives alongside your email. There are two surfaces:

• Account Drive — company-level file storage in the dashboard, managed by the account owner. Shared folders are visible to every mailbox in the account.
• Webmail Drive — per-mailbox file storage inside the webmail. Each mailbox owner gets their own private Drive plus access to any account-shared folders.

Storage is pooled — email and Drive files draw from the same plan capacity. When the composer attaches a file larger than 18 MB, TrekMail auto-routes it through Drive as a clean download link, so heavy attachments never bounce.

Drive is included on Starter, Pro, and Agency plans. The optional Drive Add-on subscription adds anywhere from 250 GB to 100 TB of pooled capacity for accounts that need it.

Common mistakes & quick fixes

• Symptom: "I can receive email but I can't send."
  • Likely Cause: You are on the Nano plan but haven't configured a custom SMTP provider yet.
  • Fix: Go to SMTP Settings and connect your own provider, or upgrade to a paid plan to use our managed sending.
• Symptom: "My emails are going to spam."
  • Likely Cause: Missing DNS records (SPF/DKIM/DMARC).
  • Fix: Check the DNS & Health tab for your domain and ensure all traffic lights are green.
