What Postdrop is
Postdrop is a web app for building and working with HTML email templates. Its HTML/CSS editor offers syntax highlighting, auto-complete, and auto-save. Users can begin with AI compose or a starter template, then edit the resulting HTML. Desktop, mobile, and dark mode previews help review a design; paid plans add live renders across email clients such as Gmail, Outlook, iOS, and Android. The app can export inlined HTML or create browser-viewable preview links that recipients can open without an account. It lists a SendGrid integration and says exports can be used with Mailchimp, HubSpot, Klaviyo, Customer.io, OneSignal, and other ESPs. Postdrop supports team sharing. The Free plan allows three templates, 10 exports per month, and 10 test emails per day for one user. The service is freemium and runs on the web.
