A
About Mailjet

Mailjet is an email service provider that combines transactional and marketing email capabilities into a single platform. It serves both marketers who need to create and send campaigns and developers who require reliable email delivery via API. Its real-time collaboration feature for email design sets it apart, allowing teams to work on templates simultaneously, similar to Google Docs. Owned by Sinch (formerly Mailgun), it's a solid choice for businesses that need both bulk marketing emails and transactional messages like receipts and password resets without juggling multiple tools.

About Substack

Substack is a publishing platform that lets writers create email newsletters and websites without needing any technical skills. Writers can offer free content, paid subscriptions, or a mix of both, keeping a direct relationship with their readers without algorithmic interference. The platform handles payments, email delivery, and hosting, taking a 10% cut of subscription revenue. It has become a popular home for independent journalists, essayists, podcasters, and niche experts who want to own their audience. While it's simple by design, that simplicity can feel limiting for creators who want more customization or advanced marketing tools.
