Postdrop
What it is
Postdrop is a web app for creating, previewing, testing, sharing, and exporting HTML email templates. Its HTML/CSS editor provides syntax highlighting, auto-complete, and auto-save. Users can start with AI compose or a starter template, then edit the resulting HTML. Desktop, mobile, and dark mode previews are available; paid plans add live renders across email clients including Gmail, Outlook, iOS, and Android. Postdrop exports clean, inlined HTML and creates browser-viewable preview links that recipients can open without an account. It lists a SendGrid integration and says exported HTML can be used with Mailchimp, HubSpot, Klaviyo, Customer.io, OneSignal, and other email service providers. Team sharing is available: Pro includes five users and Enterprise unlimited users. The Free plan includes three templates, 10 exports per month, 10 test emails per day, one user, two AI templates per month, SendGrid integration, and no live client preview credits. Solo costs $29 a month and Pro costs $79 a month. Postdrop says deleted templates remain in Trash for 30 days and may persist in backups and caches until later purged.
