(TL;DR) SendGrid alternatives at a glance

What’s “wrong” with SendGrid?

SendGrid is undoubtedly a powerful email platform with impressive technical capabilities, especially for developers who need API-first solutions. However, after analyzing hundreds of reviews online from G2, Capterra, Trustpilot, and Reddit, here were the most common issues that kept coming up:

• A drag-and-drop editor that makes designing emails difficult, especially for non-technical marketers who need visual campaign builders.
• Deliverability issues with emails often landing in spam folders or not being delivered at all, undermining campaign effectiveness.
• Poor customer support with long response times and difficulty reaching knowledgeable representatives when urgent issues arise.
• Confusing pricing structure with essential features like extended email log retention (only 3 days on basic plans) and marketing automation locked behind higher tiers.
• Account management problems, including automatic suspensions shortly after signup without clear explanations, leaving users locked out of their accounts.
