Frequently Asked Questions

An SMTP relay service routes outgoing emails through a third-party mail server to improve deliverability and bypass sending limits.
SMTP relay services such as Maileroo, Mailgun, and SendGrid clean IP addresses, authenticated domains, and reputation monitoring to ensure emails land in the inbox instead of spam.
If you send transactional emails, newsletters, or marketing emails, an SMTP relay service can help improve deliverability and ensure your emails land in the inbox.
Common authentication methods include SPF, DKIM, DMARC, and SMTP authentication. These methods help verify the sender and improve email deliverability.
Yes, but you must follow anti-spam policies to avoid throttling, blacklisting, or account suspension.
A regular email server sends emails for a single sender and cannot handle high-volume email traffic. Whereas, an SMTP relay service is designed to handle high-volume email delivery efficiently, often by using load-balancing and running clusters of MTA servers.
Most services provide analytics, including delivery rates, open rates, bounce tracking, and spam complaint reports. Maileroo offers real-time analytics and detailed reports to help you monitor your email performance.
You can configure it using SMTP credentials in your email client, application, or marketing platform, often requiring simple server settings updates.
IP warming gradually increases the sending volume over a new IP address to build a positive reputation with email providers and avoid spam filters.
SMTP relay uses the SMTP protocol to send emails, while API-based email sending allows direct integration with applications via RESTful APIs for faster and more flexible email sending.
Consider factors such as deliverability rates, authentication methods, analytics, pricing, scalability, and customer support. Maileroo offers enterprise-grade reliability and advanced features for high-volume email sending.
Popular SMTP relay services include Maileroo, SendGrid, Mailgun, AWS SES, Postmark, SMTP2GO, Resend and TurboSMTP. Each service offers unique features and pricing plans to suit different email sending needs.
