What email service should I use if I send 10k emails a month?

If you’re sending around 10,000 emails/month, the best choice depends on what kind of emails these are:

1) Marketing/newsletters

Use an email marketing service:

• Brevo (Sendinblue) – good value, easy to use
• Mailchimp – popular, but can get pricey
• ConvertKit – great for creators/newsletters
• MailerLite – simple and usually affordable
• ActiveCampaign – stronger automation, pricier

2) Transactional / app emails

Use a transactional email provider:

• Postmark – excellent deliverability for transactional mail
• Amazon SES – cheapest, but more technical
• SendGrid – common, flexible
• Mailgun – developer-friendly

Quick recommendation

• If these are newsletters/marketing: Brevo or MailerLite
• If these are password resets, receipts, alerts: Postmark or Amazon SES
• If you want simple and affordable: MailerLite

Important note

10k emails/month is not huge, but you should care about:

• Deliverability
• Spam compliance
• List quality
• Easy unsubscribe handling

If you want, I can recommend the best one based on your use case, budget, and whether it’s marketing or transactional.
