How does RelayMail work?

RelayMail uses email forwarding - you set up your email provider to forward messages to a unique RelayMail address. We then post them to your Slack channel. When you reply in Slack threads, we send the response back as an email. No email credentials are stored.

Which email providers work with RelayMail?

RelayMail works with any email provider that supports forwarding, including Gmail, Outlook/Microsoft 365, Apple Mail/iCloud, Yahoo Mail, Zoho Mail, and custom IMAP servers.

Is my email data secure?

Yes. RelayMail never stores your email credentials. We only receive forwarded emails and send replies through the Resend email infrastructure. Your original email account remains fully under your control.

Can I reply to emails from Slack?

Yes! When an email appears in your Slack channel, simply reply in the thread. RelayMail automatically sends your response as an email back to the original sender, maintaining the conversation thread.

What's the difference between Starter and Pro plans?

Starter ($10/mo) includes up to 1,000 email threads per month. Pro ($99/mo) includes up to 100,000 threads, custom sender domain support so replies come from your own email address, and priority support.

What counts as a 'thread'?

A thread is a conversation with a unique sender. If the same person emails you 10 times about the same topic, that's 1 thread. A new email from a different person starts a new thread.

Privacy Policy - RelayMail

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:

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)
Forwarded emails arrive at our servers via Resend (our email infrastructure provider)
We post the email to your connected Slack channel
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 and read replies. We cannot access your private messages, other channels, or workspace data beyond what's required for the service.

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

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)

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: Send important service updates, billing notifications
Improve the service: Analyze usage patterns to fix bugs and improve features

Data Retention

Account data: Retained while your account is active, deleted within 30 days of account deletion
Thread mappings: Retained to maintain conversation history, deleted when you delete your inbox
Email content: Processed in real-time and not permanently stored - only metadata (message IDs, subjects) is retained
Usage metrics: Retained for 12 months for billing purposes

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
