Do I need an email delivery provider for my app?

Maybe—but not always.

You need an email delivery provider if your app sends transactional or automated email and you want them to be reliable, deliverable, and scalable. Common examples:

• account verification emails
• password resets
• receipts/invoices
• notifications
• welcome emails
• alerts

Why use one?

A provider like SendGrid, Postmark, Amazon SES, Mailgun, etc. helps with:

• Deliverability: emails are less likely to land in spam
• Authentication: easy setup for SPF, DKIM, DMARC
• Tracking/logs: see bounces, complaints, opens/clicks
• Scaling: handle volume without managing your own mail server
• Reputation management: protects your domain/IP from being flagged

When you might not need one

You may not need a provider if:

• your app sends very few emails
• you only need emails for development/testing
• you’re sending through an existing platform you already use
• emails are not critical if they occasionally fail

When you definitely should use one

Use a provider if:

• email is part of your app’s core flow
• users need to reliably receive security/account emails
• you expect more than a tiny volume
• you don’t want to manage mail server deliverability issues

Can you send email without one?

Yes, technically you can:

• use your own SMTP server
• use your hosting provider’s SMTP
• use Gmail/Outlook SMTP for low-volume personal use

But for production apps, this often becomes unreliable or limited.

If you want, I can recommend the best provider based on your app type, volume, and budget.
