RelayMail

Privacy Policy

Last updated: November 11, 2026

Overview

RelayMail ("we", "our", or "us") operates a service that connects your email to Slack. This Privacy Policy explains what data we collect, how we use it, and your rights regarding your information.

Key Point: No Email Credentials Stored

RelayMail uses email forwarding - we never store your Gmail password, IMAP credentials, OAuth tokens, or any other email provider credentials. You set up forwarding in your own email provider, and we only receive emails you choose to forward to us.

How RelayMail Works

Understanding our architecture helps explain what data we handle:

  1. You set up forwarding from your email provider (Gmail, Outlook, etc.) to a unique RelayMail address we provide (e.g., inbox-abc123@relay.relaymail.app)
  2. Forwarded emails arrive at our servers via Resend (our email infrastructure provider)
  3. We post the email to your connected Slack channel
  4. You reply in Slack, and we send your response as an email via Resend

This forwarding-based model means we never access your email account directly - we only receive the specific emails you forward to us.

Information We Collect

Account Information

When you sign in with Slack, we receive and store:

  • Your Slack user ID and workspace ID
  • Your name and email address (from Slack profile)
  • Your profile picture URL

Slack Workspace Access

When you connect your Slack workspace, we store:

  • Slack bot token (allows us to post messages to your selected channel)
  • Channel ID where emails should be posted
  • Workspace ID for routing

We only request permissions needed to post messages, upload a forwarded email's attachments, read replies and read files attached to those replies. RelayMail joins only the public channel you pick (a private channel needs you to invite it) Slack sends it the messages in that channel; it acts only on replies in threads it posted and keeps none of the other messages. When someone replies, it looks up that person's Slack display name to put on the email. It cannot read your direct messages or other channels.

Email Data

When emails are forwarded to us:

  • We process: Sender address, subject line, and message body to display in Slack
  • We store: Email message IDs and subject lines for thread matching (so replies go to the correct conversation)
  • We do NOT permanently store: Full email bodies - these are processed and forwarded to Slack, then discarded
  • Attachments: Files on a forwarded email pass from Resend to that email's thread in your Slack workspace. Files a teammate attaches to a reply in that thread pass from Slack to Resend and on to the customer with the reply email. We keep no copy of either
  • When Slack can't take an email: If an inbox is over its monthly limit, its subscription has ended, Slack is disconnected or Slack refuses a message, we send that email to the inbox owner's email address instead, so it isn't lost.

Thread Mappings

To maintain conversation threads between email and Slack, we store:

  • Email message ID (unique identifier from the email)
  • Original sender's email address
  • Email subject line
  • Corresponding Slack channel ID and thread timestamp

This mapping data allows us to route email replies to the correct Slack thread and vice versa.

Billing Information

Payments are processed by Stripe. We store:

  • Stripe customer ID (links your account to your Stripe subscription)
  • Subscription ID and plan type
  • Thread usage counts (for billing limits)

After your account data is deleted, we keep only the Stripe customer ID and subscription ID, so we can handle refunds and payment disputes.

We do NOT store credit card numbers, bank details, or other payment credentials. All payment processing happens directly through Stripe's secure systems.

Usage Data

We track basic usage metrics including thread counts per month (for billing), forwarded email counts (for verification), and general service health metrics.

What We Do NOT Collect or Store

  • Email passwords - We never ask for or store your email password
  • OAuth tokens for email - No Gmail or Outlook OAuth tokens
  • IMAP/SMTP credentials - We don't use direct email server access
  • Access to your full inbox - We only receive emails you explicitly forward
  • Credit card numbers - All payment data is handled by Stripe

How We Use Your Information

  • Provide the service: Process forwarded emails and post them to Slack, send your Slack replies as emails
  • Maintain thread continuity: Match email replies to the correct Slack thread
  • Manage your account: Authenticate you, manage your subscription, enforce usage limits
  • Communicate with you: Service and billing notices, and during a trial a few emails about setup, the trial end date and the charge, and a note if you cancel. Reply "stop" to any of the trial emails and we stop sending them.
  • Learn why people cancel: If you cancel in Stripe's billing page, we read the reason and comment you choose to give there.
  • Improve the service: Analyze usage patterns to fix bugs and improve features

  • Thread mappings: Retained while your inbox is active to keep conversation history. Deleted within 30 days after termination (you delete the inbox or your subscription ends), or sooner on request to hello@greatwork.company
  • Email content and attachments: Processed in real-time and not permanently stored - only metadata (message IDs, subjects) is retained
  • Usage metrics: Retained for 12 months for billing purposes
  • Backups: Deleted data also leaves our backups, which we keep for 14 days

Data Security

We implement appropriate technical and organizational measures to protect your data:

  • All data in transit is encrypted using TLS/HTTPS
  • Database access is restricted and authenticated
  • Slack bot tokens are stored securely
