Privacy by architecture — not just policy

Your emails never touch our servers

Most tools claim to be private. We built Mailow so we structurally cannot access your email content — even if we wanted to.

What we never access: Email bodies · Attachments · Contact lists · Calendar data · Draft content · Sent mail · Personal information

Email bodies never read
We analyze metadata only — sender, subject, timestamp. Your email content stays in Gmail, untouched.
Zero email storage
Nothing from your inbox touches our database. No copies, no caching, no backups of your emails.
AES-256-GCM encrypted
Your Gmail access tokens are encrypted with military-grade AES-256-GCM before being stored.
Row-level security
Supabase RLS ensures your data is strictly isolated. No shared tables, no data leaks between users.
GDPR compliant
Full data control. Request deletion anytime. One-click disconnect removes all access instantly.
No third-party sharing
We never sell, share, or license your data. Not for ads. Not for AI training. Not ever.

Up and running in 30 seconds

Connect Gmail. Review Mailow's suggestions. Done. No new inbox to check, ever.

1

Connect Gmail

OAuth in 30 seconds. We only access metadata — never your email content. Revoke access anytime from Google settings.

2

Review your flow

Mailow analyzes 300–500 emails and proposes up to 12 smart label categories. You approve before anything is applied.

3

Stay in Gmail.

New emails auto-label every 2 minutes. One daily briefing at your chosen time. That's the entire setup.

Everything you need. Nothing you don't.

Rules first, AI second

Every correction creates a rule. Rules are free and instant. AI is only called when rules don't match. Cost trends toward zero.

Critical emails protected

Account suspensions, billing failures, security alerts — these match protected patterns and can never be archived or marked noise.

Daily flow, not an inbox

One email per day. Action required, follow-ups, FYIs — grouped and summarized. Reply directly from the digest.

Full transparency

Every label shows exactly why it was applied: "Rule: github.com", "Light AI: sender is a newsletter", "Protected: billing failure".

Pattern detection

Runs hourly. When ≥5 emails from the same domain appear without a label, Mailow suggests one. You approve; it becomes a rule.

Control via chat

"Add Dan to VIP." "Archive all from that newsletter." "Why was this labeled noise?" Natural language, instant changes.

Exactly what gets created in your Gmail

Clean labels, smart priorities, and a daily digest — all inside Gmail.

How AI usage billing works

Rules are free — they run instantly on our servers. AI classification is only used when rules don't match (uncommon senders, new patterns). We use efficient LLM models (LLaMA 3.3) and pass the savings to you. Most users see AI costs under $2/month because every correction creates a rule that prevents future AI calls.

Light (~50 emails/day)
$0–1/month AI
Rule-matched after the first week
Moderate (~150 emails/day)

Heavy variety of senders

Frequently asked questions

Mailow only reads email metadata — sender, subject line, and timestamps. We never download, store, or process email bodies, attachments, or personal content. Everything stays in your Gmail.

Start with full access to all features — no credit card required. After 14 days, choose a plan or your labels remain but auto-processing pauses. You can export all rules and data anytime.

Rules are instant and free. AI classification is only used when rules don't match. We pass our AI savings to you — most users spend $0–2/month on AI, while heavy email volume users might spend $5–8.

Absolutely. One-click disconnect removes all Gmail access. Your labels stay in Gmail (they're yours). Rules can be exported as JSON. No lock-in, no hassle.

Your Gmail tokens are encrypted with AES-256-GCM before storage. We use Supabase with Row-Level Security. No email content is ever stored on our servers — only anonymized metadata for labeling.

Every label shows exactly why it was applied. One-click corrections create instant rules so the same mistake never happens twice. Critical emails (billing, security) are protected and never auto-archived.
