About
MailerCloud is an all-in-one email marketing platform designed to help growing businesses create, automate, and optimize their email campaigns. With a library of 400+ professionally designed, mobile-responsive templates and an intuitive drag-and-drop builder, users can craft stunning emails without any coding knowledge — though a custom HTML editor is available for advanced users. The platform features a robust automation engine that supports visual workflow builders, behavior-based triggers (opens, clicks, page visits, custom events), and pre-built sequences for welcome series, cart abandonment, and re-engagement campaigns — all included on the free plan. AMP Email support lets subscribers interact with forms, carousels, and polls directly inside their inbox without leaving their email client. MailerCloud's Inbox Tracker provides real-time placement monitoring across Gmail, Yahoo, and Outlook, along with spam score analysis, sender reputation dashboards (SPF, DKIM, DMARC), and blacklist monitoring. A/B testing, contact segmentation, contact rating, personalization, dedicated IPs, and custom domains round out the deliverability toolkit. For developers, MailerCloud offers an Email API and SMTP services for high-volume transactional sending. Built-in analytics deliver granular reporting on opens, clicks, and revenue. With a 98% client retention rate and integrations via webhooks and third-party apps, MailerCloud is suited for marketers, SMBs, startups, and enterprise teams looking for an affordable, feature-rich email platform.
