Why senders trust us

Deliverability is earned. We're transparent about exactly how we access your inbox and what we do with it.

Limited Use compliant

Our handling of Gmail data follows Google's API Services User Data Policy, including the Limited Use requirements.

OAuth 2.0 only

We connect through Google's official OAuth flow. We never see, ask for, or store your password.

You stay in control

Review the exact permissions you grant and disconnect your inbox at any time — access is revoked instantly.

“We built Trustmailtoday because real deliverability comes from earning a mailbox provider's trust — gradually and honestly — not from gaming spam filters. That's the only kind of warmup we'll ever ship.”

FAQ

Questions, answered

Everything you need to know about safety, permissions, and results.

Will email warmup get my domain banned or blacklisted?

No. We do the opposite — we build legitimate sender reputation through gradual, realistic sending that mirrors organic growth. We never use spam-filter tricks or send unsolicited bulk email, which are the things that actually get domains blacklisted.

Do you read or store my emails?

We never store your password and we don't read your personal email. We only send and label the warmup messages our engine generates, so we can measure where they land. Our use of Gmail data follows Google's API Services User Data Policy, including the Limited Use requirements.

What permissions do you request, and why?

We request the minimum Gmail scopes needed: permission to send warmup emails, to label them so we can measure inbox placement, and to read your email address to identify the connected account. You can review and revoke access anytime from your Google Account.

How long until I see results?

Warmup is gradual by design. Most senders see reputation improvements within the first couple of weeks, with continued gains as volume safely ramps. Deliverability depends on factors like your domain age and authentication setup, so timelines vary.

Which email providers are supported?

We support inbox-placement tracking across Gmail, Outlook, and Yahoo. You connect your mailbox securely with OAuth — no passwords required.

Can I cancel anytime?

Yes. There are no lock-in contracts. You can disconnect your inbox or cancel your plan at any time directly from your dashboard.
