Introduction to Transactional Email Services

Are you tired of your emails mysteriously disappearing or ending up in spam folders? Your web host might be the issue, but there's a solution: specialized transactional email services. These services ensure your vital communications, like order confirmations, password resets, and account notifications, actually reach the intended inboxes.

As part of our research, we found this article on 13 Best Transactional Email Services (2025): Deliverability & Prices to be one of the most comprehensive reviews.

Here's a dive into the top 13 services for 2025, with a focus on deliverability and pricing, to help you choose wisely.

Comparison of Top Transactional Email Services

SMTP2GO stands out for its incredible value, offering a free plan of 1,000 emails per month, with paid plans at $15 for 50,000 emails. It boasts a 95.5% deliverability rate, making it an excellent choice for those who need high performance without breaking the bank. The service also provides EU hosting for GDPR compliance and has commendable customer support.

Postmark is renowned for its top-tier deliverability rate of 93.8%, making it the go-to for those who prioritize email delivery over cost. The service integrates well with ActiveCampaign and offers a free plan for sending fewer than 100 emails a month, with paid plans starting at $55 for 50,000 emails.

MailerSend offers a generous free plan of 3,000 emails monthly, with paid tiers at $30 for 50,000 emails. It's known for its solid deliverability rates and a quick approval process, with cost-effective pricing for additional emails beyond the plan limit.

Mailjet is not just for transactional emails; it also includes a newsletter editor. It provides 6,000 free emails each month and charges $35 for 50,000 emails, with an 85% deliverability rate. GDPR-compliant data hosting is a significant plus here.

SendGrid might not offer the most generous free plan, capping at 100 emails per day, but its paid plans are competitively priced, starting at $19.95 for 50,000 emails. It has decent deliverability and includes dynamic template editors, though email validation requires a more expensive plan.

Brevo (formerly Sendinblue) provides a comprehensive marketing suite, including CRM and marketing automation, with a free plan allowing up to 9,000 emails per month. Its pricing starts at $25, but the deliverability could be better.

Mailtrap started as an email testing service and now offers transactional emails with a free plan of 1,000 emails monthly and very affordable paid plans from $10. However, its deliverability can be inconsistent.

Elastic Email offers low prices but struggles with deliverability, particularly due to its shared IP policy for free users. Paid plans start at $15 for 50,000 emails, and they offer live chat support.

Zepto by Zoho is the least known but offers the lowest pricing at $2.50 per 10,000 emails.

Mailgun and Amazon SES cater more to developers or those already entrenched in their respective ecosystems. Mailgun's trial gives 5,000 free emails for one month, while Amazon SES is cost-effective at $0.10 per 1,000 emails but requires significant AWS expertise.

Mailchimp Transactional is only available as an add-on for Mailchimp users, starting at $20 for 10,000 emails, making it one of the pricier options.

SMTP lacks a free trial but offers plans from $25 per month for 50,000 emails. Its refund policy is less than ideal due to a hefty admin fee.

Recent Updates (2025):

Recent posts on X have highlighted Resend and Mailgun as budget-friendly for small-scale sending, while SendGrid is recommended for scaling up due to its volume handling. Web reviews continue to laud SMTP2GO for its value, especially for its high deliverability and free tier.

Conclusion

The choice of a transactional email service should be about ensuring your emails reach their destination. SMTP2GO offers the best value for money, Postmark excels in deliverability, SendGrid is ideal for large volumes on a budget, and Mailjet is perfect if you need both marketing and transactional capabilities. Remember, it's not just about sending emails but making sure they're received, opened, and acted upon. Choose wisely to enhance your communication strategy.
