Do I need a dedicated IP for app email sending?

Not necessarily.

You only need a dedicated IP for app email sending if you have specific deliverability, volume, or reputation-control needs. For many apps, a shared IP is perfectly fine.

Use a shared IP if:

• You send low to moderate volume
• You’re just starting out
• Your emails are mostly transactional (password resets, receipts, notifications)
• You want simpler setup and lower cost

Consider a dedicated IP if:

• You send high volume
• You want full control over IP reputation
• You send a large mix of transactional and marketing email and want isolation
• Your sending patterns are consistent enough to warm up the IP properly

Important note:

A dedicated IP is not automatically better. If you send too little email from it, deliverability can be worse because the IP won’t build enough reputation.

Common recommendation:

• For most apps: start on a shared IP
• Move to a dedicated IP later if you outgrow it or need more control

If you want, I can also help you decide based on:

• your monthly sending volume
• transactional vs marketing email
• which provider you use (SES, SendGrid, Mailgun, Postmark, etc.)
