Connect through API or SMTP?

To send emails through Inboxroad, you have two options: connecting through API or SMTP. Both options have their advantages and disadvantages, and which one you choose will depend on your specific needs.

Which option should you choose: API or SMTP?

Choosing between API and SMTP will depend on your specific needs and technical expertise. If you have a development team and want complete control over your email campaigns, connecting through API may be the best choice. On the other hand, if you’re looking for a simpler solution and don’t have as much technical expertise, connecting through SMTP may be the better option.

Regardless of which option you choose, Inboxroad offers step-by-step guides to help you get started. And if you need a custom integration, our team is always here to help.

Connect through Inboxroad using API

Connecting through Inboxroad’s API is a powerful option for those with technical expertise who want full control of their email campaigns. With the API, you can programmatically access and analyze critical email data to enhance your email deliverability rates and optimize your email marketing campaigns. The API allows you to retrieve detailed information about email bounces and complaints, monitor email deliverability statistics, and implement bounce and complaint-handling mechanisms in your applications. Inboxroad provides a comprehensive step-by-step guide to getting started with the API, and our team is available to assist you if you need a custom integration.

Sending emails using SMTP protocol

SMTP, or Simple Mail Transfer Protocol, is the standard protocol for sending email over the internet. Connecting to Inboxroad through SMTP allows you to send emails using your own email client or email marketing software.

Connecting through SMTP is generally easier and requires less technical expertise than connecting through API. However, it may not offer the same level of customization and control as the API. Here is our guide in order to set up the SMTP.
