How to move from SMTP.com to a new platform
Migrating from SMTP.com is straightforward. Follow these steps to protect deliverability and complete a smooth transition.
Export suppression lists, bounces, and logs from SMTP.com to avoid resending to problematic addresses.
Add and verify your sending domains on the new platform. Set up SPF, DKIM, and DMARC to keep reputation and compliance.
Transfer templates (export/import or rebuild). For marketing or triggered sends, migrate contact lists while honoring privacy and opt-in status.
Send test messages to validate inbox placement, formatting, and tracking. Run spam and preview tests to resolve issues before switching over.
Update your app to use new SMTP/API credentials. Monitor closely and keep SMTP.com active as fallback until you confirm performance.
The best alternative depends on your primary use case. For developer-driven teams needing robust API and regional data control, Mailgun is a top choice due to deep analytics, scalable infrastructure, and per-domain EU/US residency.
For those that only require US-hosting and limited analytics, Postmark is a solid option.
For an all-in-one platform that combines email, SMS, and marketing automation, Brevo is a strong contender for teams in the EU.
Elastic Email is typically the lowest cost at scale. MailerSend and SMTP2GO also offer low entry pricing with clear overage rates, making them affordable for small and growing businesses. Mailgun offers a free plan with 100 emails/day with plans that scale as you grow.
Mailgun (per domain), Brevo (EU by default), SMTP2GO (EU option), MailerSend (EU by default), and Elastic Email (EU data centers) all support EU data residency. Postmark is US-only.
Yes. Mailgun, Brevo, SMTP2GO, Elastic Email, MailerSend, and Postmark each provide free tiers suitable for testing or low-volume use, making it easier to get started before committing. However, the limits on these plans vary significantly in terms of monthly email volume, daily sending caps, and feature availability. You should always review the current terms on their pricing pages to ensure the free tier meets your needs for testing or low-volume sending.
No. You can export suppressions and logs, set up SPF/DKIM/DMARC, migrate templates, send deliverability tests, and switch credentials. Most teams complete migration in just a few hours.
In the short term, it’s important to warm up new IPs and domains and keep your lists clean. Many businesses find their deliverability improves after switching to a platform like Mailgun with more advanced tools.
Mailgun is ideal for technical teams who require granular control, powerful analytics, and compliance features like selectable EU/US data residency. It’s built for reliability at scale. Postmark is highly regarded for its exceptional delivery speed and developer-friendly experience for purely transactional email, but it is limited to US-only data hosting.
Focus on deliverability, data residency, integration ease, support responsiveness, and transparent pricing—especially regarding dedicated IPs and log retention. These are critical for long-term email program success.
