If your goal is better email deliverability, the best provider depends on what you’re sending:
For transactional email
Use one of these:
- Postmark — often considered the best for deliverability and reliability
- Amazon SES — very strong deliverability, especially if configured well
- Mailgun — solid, flexible, good tooling
- SendGrid — widely used, but deliverability can vary more by setup/account
For marketing email/newsletters
Use:
- Brevo (Sendinblue)
- Mailchimp
- Klaviyo if you’re ecommerce-focused
- ConvertKit for creators
If deliverability is the main priority
My usual recommendation is:
- Postmark for transactional
- Amazon SES if you want low cost and can manage setup
- Klaviyo/Brevo for marketing
Important note
Deliverability is not just the provider. It also depends on:
- proper SPF, DKIM, and DMARC
- your sending reputation
- list quality
- bounce/complaint rates
- email content and frequency
If you tell me:
- whether this is transactional or marketing,
- your current provider, and
- your volume,
I can suggest the best option for your case.
