Madhya Pradesh, India
What it is
PostBrix is a browser-based email builder for creating responsive templates and organizing campaign-ready assets. Its drag-and-drop editor uses blocks such as text, images, buttons, dividers, and columns, so users can build emails without HTML knowledge. Layouts are designed for mobile and desktop, and headers, footers, and calls to action can be saved for reuse. AI assistance can generate or refine email copy. Finished templates can be exported as MJML or fully inlined HTML for an existing email workflow. PostBrix names Mailchimp, HubSpot, SendGrid, Brevo, Postmark, Amazon SES, Klaviyo, Customer.io, ActiveCampaign, and Mailgun as services compatible with its exported code. Documentation covers template rendering through a REST API, API key management, live previews, test emails, responsive checks, and rendering troubleshooting. The free plan includes three projects, one workspace, 50 MB of storage, five monthly exports, and ten lifetime AI generations. It also limits daily downloads to five and test emails to three. A free trial is listed, and paid plans start at $9/mo. PostBrix identifies marketing teams, SaaS companies, and agencies among its users.
