Everything you need to send from Gmail at scale.
OAuth-secured sending, automatic warm-up, and full deliverability tooling for every connected Google account.
Connect Gmail and Google Workspace in under 60 seconds via Google OAuth 2.0 with scopes gmail.send, gmail.readonly, and gmail.modify, no app passwords, no SMTP credentials.
Send through the Gmail API users.messages.send endpoint at a 250 quota unit per send rate, well under the 250 unit per second per user cap and the 1.2 billion daily project quota.
Warm every connected Gmail inbox automatically with organic-looking conversations between Navigent accounts to build sender reputation for 14 to 21 days before live cold sends.
Rotate sends across 5, 10, or 50 connected Gmail accounts with per-mailbox daily caps (default 40 cold sends per day), weekend pause rules, and 24-hour cooldowns after each reply.
Verify SPF, DKIM, DMARC, BIMI, and MTA-STS records at connect time with a live deliverability checklist that flags missing or misaligned records before any campaign launches.
Detect bounces and replies via Gmail API push notifications on the watch endpoint in real time: hard bounces auto-suppress, soft bounces retry with exponential backoff up to 5 attempts.
Triage replies across every Gmail account plus LinkedIn, WhatsApp, Instagram, and SMS in one unified inbox with AI intent labeling (interested, not now, wrong person, opt out).
Monitor reputation per domain and per mailbox: spam-folder rate, primary-tab placement, Postmaster Tools sender score, complaint rate, and IP reputation with daily Slack alerts.
Send on per-Gmail-account schedules with timezone-aware windows, custom working hours, and randomized 30 to 90 second human-paced delays between sends to mimic a human SDR.
Pause automatically on Gmail rate limits (429 Too Many Requests), quota warnings, or bounce spikes above 4%, with Slack alerts to the right channel before a domain gets blacklisted.
Apply custom tracking domains per Gmail account with auto-issued Let's Encrypt SSL so opens and link clicks don't leak through Google's shared tracking infrastructure.
Ship GDPR and SOC 2 Type II ready with Gmail thread data in your chosen EU or US region, encrypted in transit (TLS 1.3) and at rest (AES-256) with per-user audit logs.
Frequently asked questions
How do I connect Gmail to Navigent.io?
+
Sign in to Navigent, open Settings, Integrations, Gmail, and click Connect with Google. The OAuth flow completes in about 60 seconds and authorizes send, read, and label scopes on the selected mailbox.
Does Navigent use OAuth or app passwords for Gmail?
+
Navigent uses Google OAuth 2.0 exclusively. App passwords and IMAP credentials are not supported because OAuth provides safer token rotation, audit logging, and revocation.
What are the daily Gmail sending limits when using Navigent?
+
Free Gmail accounts can send roughly 500 emails per day, while Google Workspace accounts allow up to 2,000 per day. Navigent enforces conservative per-mailbox throttles to keep you well below those caps.
Does Navigent include Gmail email warmup?
+
Yes. Warmup is included on every plan and gradually ramps inbox-to-inbox replies, opens, and folder moves to build sender reputation before scaled outreach.
How does Navigent verify SPF, DKIM, and DMARC for Gmail?
+
During Gmail setup Navigent runs an automated check against your sending domain and flags missing or misaligned SPF, DKIM, and DMARC records. The dashboard shows the exact DNS entries to add so deliverability stays healthy.
Can I connect multiple Gmail mailboxes to one workspace?
+
Yes. Solo includes 1 mailbox, Pro supports up to 5 across the team, and Agency supports unlimited mailboxes across unlimited workspaces.
Will recipients see emails as sent from my real Gmail address?
+
Yes. Messages are sent through the Gmail API using your authorized address, so replies thread natively in Gmail and appear in your Sent folder with full headers.
What should I do if my Gmail connection disconnects or tokens expire?
+
Open Settings, Integrations, Gmail and click Reconnect to refresh the OAuth token. Disconnects usually happen after a password change, 2FA reset, or a Google security review and reconnecting restores sync in under a minute.
