Deliverability Guide

Best practices for maximizing email deliverability with Motorical.

DNS Authentication​

Proper DNS configuration is the foundation of good deliverability.

SPF Record​

Authorize Motorical to send on behalf of your domain:

Type: TXT
Name: @
Value: "v=spf1 include:mail.motorical.com ~all"

DKIM Record​

DKIM signing is automatically configured when you verify your domain. The DKIM selector and public key are provided in your domain setup.

DMARC Record​

Set a DMARC policy to protect against spoofing:

Type: TXT
Name: _dmarc
Value: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

Start with p=none for monitoring, then move to p=quarantine or p=reject after reviewing reports.

Monitoring Deliverability​

Provider-Level Analytics​

Check deliverability per mailbox provider:

curl -H "Authorization: Bearer $TOKEN" \
  "$BASE_URL/motor-blocks/$BLOCK_ID/providers?from=2024-01-01T00:00:00Z&to=2024-01-08T00:00:00Z"

Domain Health​

Monitor your domain's authentication status:

curl -H "Authorization: Bearer $TOKEN" \
  "$BASE_URL/motor-blocks/$BLOCK_ID/domain-health"

Error Code Analysis​

Identify delivery issues by SMTP response code:

curl -H "Authorization: Bearer $TOKEN" \
  "$BASE_URL/motor-blocks/$BLOCK_ID/error-codes?from=2024-01-01T00:00:00Z&to=2024-01-08T00:00:00Z"

Best Practices​

Content​

  • Avoid spam trigger words in subject lines
  • Maintain a good text-to-image ratio
  • Include a clear unsubscribe mechanism
  • Always include a plain-text alternative

Sending Patterns​

  • Warm up new domains gradually (Motorical handles this automatically)
  • Maintain consistent sending volume
  • Avoid sudden volume spikes
  • Respect rate limits

List Hygiene​

  • Remove hard bounces immediately
  • Process unsubscribe requests promptly
  • Regularly clean inactive subscribers
  • Validate email addresses before importing

Infrastructure​

  • Monitor bounce and complaint rates
  • Set up webhooks for real-time bounce notifications
  • Use separate Motor Blocks for transactional vs marketing email
  • Review provider-specific deliverability regularly
