1. Signup for a free account
Head over to https://signup.mailgun.com/new/signup and create your account. Follow the guided setup to activate your account. Once you've clicked the verification link in your email, you can now send emails from that email address.
2. Send your first email
Create your first campaign at https://app.mailjet.com/campaigns. Pick from the list of templates, or create your own.
3. Check your inbox
Your email should arrive in a few seconds. If you did not receive it, check your spam folder, or the logs for more information
Once that you've seen how easy it is, the next steps are to set up your account for sending in mass.
Sending in Bulk
There are 2 things you'll need to setup for sending.
1. Importing your contacts
In order to send to a larger list of contacts, simply add them via https://app.mailjet.com/contacts. You can upload them in bulk using the following formats: .csv, .txt or .rtf
2. Setting up a verified sender
The email you signed up with was automatically added as a verified sender. To add more, do so at https://app.mailjet.com/account/sender.
Alternatively, you can verify the entire domain, allowing you to send from any address tied to that domain with no further validation. Note that you will need access to your website hosting, or domain registration account in order to do so.
Why is verification important?
Verifying your domain improves deliverability, reducing the chances that your email ends up in the Spam folder.
For our Transactional Email Users
The starting steps are the same as above. You'll need to create an account, and get the domain or sender address verified.
Sending an email
You have 2 options to send Transactional Emails
Option 1 - Send Email API
To send an email via the API, do a POST request on /v3.1/send with this sample payload.
