SendX is email marketing software for sending campaigns, building subscriber lists and automating marketing messages. The company says more than 3,000 businesses use it and that it has delivered over 4.4 billion emails. Its main pitch is unlimited marketing sends combined with an AI sending engine meant to keep emails out of spam folders.
The platform is powered by SendPost, a separate product from the same company that offers an Email API and SMTP relay. SendX also reports a 4.6 out of 5 rating on G2 and Capterra, a figure Gappsy has not independently checked.
Subscribers come in through signup forms, landing pages and popups, and land on lists inside SendX. You then build emails in a drag-and-drop editor, send one-off newsletter campaigns or drip sequences, and set up visual workflows that react to triggers and conditions.
Behind the scenes, an AI sending engine monitors sender reputation and adjusts throttling automatically. SendX claims this keeps inbox placement at 95-98%. Real-time analytics then report opens, clicks and conversions, and the results feed back into later campaigns.
The core tools include newsletter campaigns with smart sending times and spam testing, A/B split tests with automatic winner selection, and visual workflows with conditional logic and multi-channel sequences that include SMS. Segmentation uses behavior, demographics, custom fields and tags, with GDPR tools built in.
List growth tools include embedded forms, landing pages with custom domains and SSL, and exit-intent popups. Add-ons cover Auto Warmup, Email List Cleaning, Dynamic Sender, Custom Reply and a Bot Open/Click Tracker. Developers get a RESTful API, webhooks, SDKs and a sandbox.
