Shortwave vs. ActiveCampaign Postmark

Shortwave is the smartest email app on planet Earth. Email is the backbone of modern business communications. Every day, billions of emails are exchanged inside and between businesses discussing everything from investment decisions, to high-stakes negotiations, to product designs, to major purchases. Email is the one tool that connects everyone — employees, customers, vendors, even the CEO. The biggest decisions are made in the email inboxes of business leaders. And yet, the inbox you rely on every day has not fundamentally improved in over a decade.

Postmark is the email delivery service that people actually like. Stop worrying if your emails made it to the inbox, and get back to focusing on what matters—building great products. Start sending in minutes: With API libraries for pretty much every programming language you can think of, Postmark fits seamlessly into any stack. Stellar deliverability (without paying for a dedicated IP): You might say that Postmark has serious street cred with inbox providers.
