SMTP Service
Optimize Email Delivery with High-Performing SMTP Service
Say goodbye to the hassles of managing your own SMTP servers with INBOX. Save time and money by opting for our cloud-based SMTP service, designed to simplify your email program and future-proof your communications. With INBOX, you no longer have to worry about hardware, maintenance, and other overhead costs, as we handle everything in-house, leaving you free to concentrate on your core business.


What is an SMTP Server?
SMTP is a communication method between servers for sending and receiving emails. Authentication is necessary for SMTP servers, which may include a username, password, IP address, ports, and security protocol such as SSL or TLS. After adding and authenticating your domain name, Mailgun provides you with all the necessary details, making it simple to begin sending emails via your application’s SMTP email client.
Real-time email tracking and advanced analytics of your email program
Real-time email tracking and advanced analytics enable you to gain valuable insights into the performance of your email program. With this information, you can optimize your email campaigns, improve engagement rates, and boost conversions.


Advanced deliverability features to reduce bounce rates and spam complaints
INBOX’s advanced deliverability features reduce the likelihood of your emails being marked as spam or bouncing. Our tools ensure your emails meet industry best practices and deliverability standards, increasing your email program’s overall success rate. By proactively monitoring your email sending and performance, we help you maintain a strong sender reputation and achieve high email deliverability rates.
Simplify your incoming message management with INBOX
By configuring your SMTP setup and using routes, you can streamline your inbound email streams and enhance readability. Routes allow you to parse and convert inbound messages to UTF-8, decluttering email threads and making them easier to read. Additionally, our advanced processing technology can convert complex MIME data from incoming messages into simple JSON, making inbound message handling effortless for your business.
