We think you should make an informed decision. Here's our honest take on where MailerSend falls short — and what it genuinely does well.
When a prospect needs only low-volume transactional emails (under 50k/month), has no bulk sending requirements, and wants simple API integration without advanced deliverability features.

Everything you need to know about SendPost and transactional email delivery
MailerSend works well for basic transactional emails at low volumes. But when you need to scale to millions of emails, SendPost provides the automated deliverability tools, proactive monitoring, and enterprise infrastructure that MailerSend lacks. We automate IP warmup, provide real-time alerts, and handle high-volume sending that MailerSend simply cannot support.
Yes! Unlike MailerSend's transactional-only focus (limited to 500 emails per bulk request), SendPost is built to handle both transactional messages and high-volume bulk sending with the same enterprise-grade infrastructure and deliverability tools.
Absolutely. SendPost automatically manages IP warmup with intelligent throttling based on ISP-specific sending limits. MailerSend requires manual volume management, which can lead to deliverability issues if not done correctly.
MailerSend may appear cheaper initially with their free tier and low entry pricing. However, costs escalate quickly with overage charges, and users report account suspensions with no refunds. SendPost has a higher entry point but becomes the most cost-effective solution at scale with predictable pricing and no surprise charges.
SendPost provides automated IP warmup, real-time deliverability alerts for bounce spikes and SMTP errors, granular IP and domain reputation monitoring, years of log retention with advanced filtering, and proactive recommendations. MailerSend offers basic dashboards but no automated alerting or advanced monitoring capabilities.
Definitely. MailerSend is designed for low-volume transactional emails and limits bulk sends to 500 emails per request. SendPost infrastructure handles millions of emails with dynamic IP pool management, intelligent routing, and automated reputation protection. If you're sending over 100k emails monthly, SendPost is the clear choice.
