  • Building a (Virtual) Events Site
    MailJet is a recent addition to the site. Mailing lists can get very expensive. In fact, the mailing list was by far the single most expensive item on this list but Mailjet helped with that.

I then went to ActiveCampaign, which I used... - Source: dev.to / almost 3 years ago
  • Adding a Mailing List Subscription with Mailjet and Netlify Functions
    I moved from Mailchimp some years back because the cost was going to be a major burden, especially once they changed how they calculate their pricing (anyone you've been in contact with, even if they are unsubscribed and you aren't allowed to communicate with them, counts against your cap). At the time, ActiveCampaign was a cheaper but still full featured option. However, I never really needed all the features... - Source: dev.to / about 3 years ago

  • How does your SaaS handle transactional vs promotional emails?
    Email is hard. I spent a couple of days trying to figure out what would be a good fit for Disk Notifier. In the end, I settled for Mailjet. They showed leadership with creating MJML (an email template language) and support transactional email well. They also have a GUI for creating emails and a free tier. Source: almost 5 years ago
