What is SMTP and How Does Mailjet Simplify It?

SMTP, or Simple Mail Transfer Protocol, is essentially the technology that powers the sending of emails from your application or server to recipients’ inboxes. Bulk emails—often marketing newsletters, notifications, or transactional messages—require a robust SMTP service to prevent failures, delays, or limitation issues. Mailjet provides a free SMTP relay that acts as an intermediary, handling the dispatch of large volumes of emails for you, while offering important features like authentication, bounce handling, and spam protection. This means you get reliability and security without building complex infrastructure yourself.

Getting started with Mailjet’s free SMTP for bulk emails is quite straightforward. Below is a comprehensive guide to walk you through the process:

1. Create and Verify Your Mailjet Account

First, go to Mailjet’s official website and sign up for a free account. You’ll need to verify your email address and sometimes your phone number depending on the region. This verification strengthens deliverability and ensures compliance with anti-spam regulations.

2. Set Up Domain Authentication

For bulk emails, domain authentication is critical. Mailjet uses SPF, DKIM, and DMARC protocols to confirm you are the legitimate sender. After creating your account, navigate to the “Sender Domains” section. You will be guided to add DNS records to your domain’s configuration:

Authentication Type Purpose Typical DNS Record
SPF Authorizes Mailjet to send emails on your behalf v=spf1 include:spf.mailjet.com ~all
DKIM Cryptographically signs outgoing messages Provided by Mailjet (varies)
DMARC Policy for handling unauthorized emails v=DMARC1; p=none

After adding these records to your DNS hosting provider, verify them using Mailjet’s tools.

3. Generate SMTP Credentials
