The email warmup tool that builds real reputation
Automatically warm up your mailbox with gradual, realistic sending and live reputation tracking — built on legitimate deliverability, not spam-filter tricks.
A cold mailbox with no sending history is treated with suspicion by Gmail, Outlook and Yahoo. An email warmup tool fixes that by sending and engaging with mail on your behalf, slowly increasing volume until providers trust your domain. Trustmailtoday does this the honest way — and shows you the results in real time.
Gradual, human-like warmup
Volume ramps day by day from a safe baseline so mailbox providers see steady, organic growth instead of a spammy spike.
Live reputation scoring
A 0–100 score built from real signals — authentication, bounces, complaints, placement and engagement — so you always know where you stand.
Inbox placement tracking
See whether your test mail lands in Primary, Promotions or Spam, plus SPF/DKIM/DMARC results, before you run a real campaign.
Why you need email warmup
Mailbox providers score every sender. New domains, new mailboxes and senders who suddenly increase volume all look risky — and risky mail gets filtered to spam or throttled.
Warmup establishes a positive track record. By sending small, steady, engaged volumes that grow over time, you teach providers that your mail is wanted, which lifts your inbox placement before you ever launch a campaign.
How Trustmailtoday's warmup works
Connect your inbox securely with Google OAuth — no passwords, ever. Our engine then runs a gradual ramp, sending warmup messages and measuring where they land.
As the ramp progresses, your reputation score climbs and you can watch the factor-by-factor breakdown improve. You stay in control and can disconnect at any time.
Frequently asked questions
Is email warmup safe?
Yes — when done legitimately. We never use spam-filter tricks or send unsolicited bulk email. We build reputation through gradual, realistic sending that mirrors organic growth, which is exactly what protects your domain.
How long does warmup take?
Warmup is gradual by design. Most senders see reputation improvements within the first couple of weeks, with continued gains as volume safely ramps. Domain age and authentication setup affect the timeline.
