Warm unlimited Gmail, Google Workspace, Outlook, Microsoft 365, and custom-domain inboxes automatically on every connected account.
Monitor SPF, DKIM, DMARC, BIMI, and major blacklist status in real time with alerts the moment any deliverability signal dips below threshold.
Ramp daily send limits automatically as reputation improves, with no manual ladder or per-mailbox tuning needed by your team ever.
Rescue spam-folder placements with positive replies happening across the warm-up network, not just inbound deliverability monitoring.
Alert instantly the moment any inbox lands in spam, with one-click remediation steps and DNS fix guides per provider per record.
Track primary-tab rate per inbox, per campaign, per day on a heat-map dashboard with week-over-week deltas surfaced automatically.
Pause any inbox whose reputation drops below your set threshold so one bad mailbox does not poison the rest of the rotation pool.
Adjust warm-up patterns per provider: Gmail, Outlook, and Microsoft 365 each follow different anti-spam rules and ramp curves.
Exclude senders below threshold from live Campaign rotation automatically until reputation recovers to safe send range threshold.
Flag missing SPF, DKIM, or DMARC records on connect before your first cold email goes out the door from a fresh new domain.
Respect per-domain rate limits and platform anti-spam policies by default with no extra configuration required per workspace.
Land in the primary tab 98% of the time on warmed inboxes after the standard 14 to 21 day ramp across every connected sender.
Frequently asked questions
What is Navigent inbox warmup?
+
Inbox warmup gradually builds sender reputation for new Gmail or Outlook mailboxes by exchanging real-looking conversations with a network of trusted inboxes. Reputation usually hits production-ready in 14 to 21 days.
Does Navigent monitor SPF, DKIM, and DMARC?
+
Yes. The deliverability dashboard checks SPF, DKIM, DMARC, BIMI, and MX records every 6 hours and flags drift the moment it occurs. One-click DNS fix generates the exact records you need to paste into your domain provider.
How does blacklist monitoring work?
+
Navigent checks your sending domain and IP against 80+ major RBLs every hour and sends Slack or email alerts within minutes of a listing. Most listings include a one-click delist request workflow.
Can warmup work on Gmail and Outlook in 2026?
+
Yes. Warmup runs on Gmail, Google Workspace, Outlook, Microsoft 365, and any IMAP/SMTP mailbox. Per-mailbox throttling stays within current Gmail (2000 per day) and Microsoft (10000 per day) caps.
How is Navigent warmup different from Mailreach or Lemwarm in 2026?
+
Mailreach and Lemwarm are standalone warmup tools at $25 to $59 per mailbox per month, while Navigent warmup is bundled at no extra cost on Pro and Agency plans. Navigent also includes SPF, DKIM, DMARC monitoring with one-click DNS fixes.
Should I warm up an inbox if I'm only sending to opt-in lists?
+
Yes. Even with opt-in lists, a new sending domain has zero reputation, and warmup builds the baseline engagement signals that mailbox providers look for. Skip warmup and you risk landing in spam from day one.
How many inboxes can I warm up at once?
+
Solo includes 1 warming inbox, Pro includes up to 25, and Agency includes unlimited inboxes across all client workspaces. Every warming inbox uses dedicated peer pools, no shared reputation.
Does warmup stop automatically when reputation is healthy?
+
Warmup keeps running at a maintenance level (typically 10 to 20 conversations per day) even after the inbox is production-ready, which holds reputation steady during heavy sending. You can pause warmup any time.
Connect an inbox and start warming up in 60 seconds.
OAuth in, hit start, and watch your domain reputation climb day one. Warm-up included on every plan from $99/mo. 14-day free trial, no credit card required.
