SendGrid (part of Twilio) is one of the most widely integrated email APIs, with mature deliverability infrastructure and clear documentation that developers consistently praise. Its marketing-campaign UI is far less polished than dedicated marketing email tools, so many teams use it purely for transactional sending.
