Frequently Asked Questions

Got questions about MakeSMTP? We've got answers to help you make the right decision for your business.

MakeSMTP is a transactional email delivery service that helps businesses reliably send time-critical emails like password resets, order confirmations, and notifications. We provide both SMTP and API endpoints that you can integrate with your applications to send emails. Our infrastructure is optimized for deliverability, ensuring your important messages reach their destinations.

MakeSMTP offers a 99.9% delivery guarantee for all transactional emails. We maintain strong sender reputations, automatically handle email authentication (SPF, DKIM, DMARC), and continuously monitor our infrastructure to ensure maximum uptime and deliverability. Our sophisticated systems automatically handle bounce processing, feedback loops, and ISP throttling to optimize delivery across all major email providers.

Yes, our Free Forever plan gives you 10,000 emails per month at no cost, with no expiration date. You get access to our API, SMTP services, and basic analytics forever. The main limitations are the monthly email volume (10,000) and access to advanced features like dedicated IP addresses, custom domains, and priority support, which are available on our paid plans.

If you exceed your plan's monthly email limit, we don't automatically charge you for overages. Instead, we'll notify you when you reach 80% and 95% of your limit, giving you the opportunity to upgrade to a higher tier. If you stay on the Free plan and exceed 10,000 emails, additional emails will be queued until the start of your next billing cycle. For paid plans, you can enable automatic overage billing at a rate of $1 per 1,000 additional emails.

Yes, all plans allow you to send from your own domain. We strongly recommend setting up domain authentication (SPF, DKIM, and DMARC records) to maximize deliverability. Our interface provides easy-to-follow instructions for configuring your DNS settings, and our support team is available to help with the setup process. For Business and Enterprise plans, we offer dedicated sending domains with pre-configured authentication.

MakeSMTP offers multiple integration options to fit your tech stack:

REST API with client libraries for JavaScript, PHP, Python, Ruby, Java, and .NET
SMTP integration with any email-sending library or framework
Direct plugins for popular platforms like WordPress, Shopify, and Magento
Webhook notifications for real-time tracking of email events

Our comprehensive documentation includes code examples and step-by-step guides for all integration methods.
