Your app or email client must be able to send transactional and marketing emails, and you want the process to be as easy to use and deploy as possible. And it is at this point when SMTP is utilized.

SMTP definition

SMTP is an abbreviation for Simple Mail Transfer Protocol, and it is used to send, receive, and reroute email messages between computers. The default SMTP servers in Gmail, for example, are capable of being replaced with platforms such as Mailslurp. If you wish to send a significant number of emails, your emails will be routed through Mailslurp's STMP servers, which can be handy if you want to send a massive number of emails.

SMTP servers require a login and passcode, as well as the SMTP server address, ports, and protocol, which is often SSL or TLS, in order to function. Mailslurp provides you with all the necessary information when you have entered the domain you wish to send emails.

Email APIs are more efficient than SMTP servers since they are less complicated to use. APIs can handle requests much more quickly than SMTP services, which is useful when delivering large numbers of emails at the same time.

SMTP Relay

Using an SMTP relay provider makes the process of sending emails much simpler. After you have added and verified your domain name, you should set up your SMTP server. All you need is your login and password, as well as the hostname and port of your SMTP server. Simply include them in your application's SMTP setup, and you'll be ready to send emails. Depending on the port, you can choose between a standard or an SSL link for data protection.

Why do you need SMTP?

Accessible Email API

You should consider using an HTTP API instead of a third-party SMTP interface if you don't already have one, as it is more versatile and scalable. Thanks to its capabilities, you can manage your mail server and digital marketing with relative ease. The majority of libraries support a variety of languages, including Java, C#, Python, Ruby, and others.

Boosting Delivery

Improve the deliverability of your emails by using an SMTP relay and email service. They can assist you in customizing SPF, DMARC, and DKIM records in order to verify your domain names. By utilizing SMTP, you will have access to an email address validation API, which will help to reduce bounce rates and spam issues. A managed email delivery solution provides professional, one-on-one assistance and monitoring to help you boost your deliverability rates even further. Use a service like MailSlurp to test email deliverability with real email addresses.

Eases the processing of incoming Emails

Messages are received in UTF-8 format, which is then MIME converted into JSON. In addition to sending email content to your app, you may automate reply handling, route spam to a filter, and many other things.

Keep track of email events

Utilize a simple control panel to monitor detailed logs and stats on promotional and transaction emails that are sent over an SMTP server and to examine particular email events such as delivery problems, clicks, and unsubscribes that occurred. Analytics allow you to analyze A/B tests, assess the efficacy of your email marketing campaigns, and improve the efficiency of your subsequent email marketing campaigns.

SMTP email delivery services are there to help you better manage email delivery, and now you know what they are and how they help.
