Email Providers

Mailpipe works with all major email providers. Choose the one that best fits your needs and follow the setup guide below.

Choosing a Provider

Each provider has different strengths. Here's a quick comparison to help you decide:

Provider Setup Guides

Common Configuration

DNS Records

Regardless of your provider, you'll need to set up these DNS records:

# MX Record - Points your domain to your email provider
@ MX 10 [provider-mx-server]

# SPF Record - Authorizes your provider to send email
@ TXT "v=spf1 include:[provider] ~all"

# DKIM Record - Email authentication
[selector]._domainkey TXT "v=DKIM1; k=rsa; p=[public-key]"

# DMARC Record - Email policy (optional but recommended)
_dmarc TXT "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

Webhook Security

Each provider signs webhook requests differently. Mailpipe automatically verifies signatures to ensure webhooks are legitimate:

• Postmark: Basic auth token in webhook settings
• Mailgun: HMAC signature with your API key
• SendGrid: Signed Event Webhook verification
• Resend: Webhook secret in headers
• AWS SES: SNS message signature verification

Switching Providers

One of Mailpipe's key benefits is provider flexibility. To switch providers:

1. Set up the new provider following the guide above
2. Update your DNS MX records to point to the new provider
3. Update your Mailpipe webhook configuration
4. Remove the old provider configuration

Your existing emails remain in your Supabase database. No data migration needed.
