Computed from our datasets · InboxRatio Editorial
This page compares 7 marketing and transactional email platforms from the InboxRatio catalog, listed with measured deliverability first and catalog demand order after that. 6 of them have a measured deliverability score from our own seed-list inbox placement tests; the remaining one shows “Not yet tested” until its test cycle completes. By price level, 5 are SMB ($$); 2 have no level assigned yet. Every one sends campaigns and transactional or SMTP email from the same account, and the catalog also lists 6 under SMTP providers, 1 under email API services and 1 under omnichannel marketing platforms. All 7 have user ratings collected from Trustpilot, G2 and Capterra, with Trustpilot counting for half; ratings are context and never feed the deliverability score. Counts, scores and order are computed from the same datasets as each service profile, so this page updates as new test cycles and data checks land. Plan-by-plan prices sit on the linked pricing pages.
