Postdrop is a web-based HTML email editor and testing workspace for developers, marketers, and teams. It combines an HTML/CSS editor with syntax highlighting, autocomplete, and autosave; desktop, mobile, and dark-mode previews; live email-client renders; inbox test emails; shareable HTML and live-preview links; CSS inlining; and clean HTML export. It is suited to teams that need to create, review, and share email templates from a browser, particularly when client-specific rendering is part of the workflow.

The freemium pricing structure starts with a Free plan offering 3 templates, 10 exports per month, 10 test emails per day, dark-mode preview, and 2 AI templates per month. Solo costs $29 per month with annual billing and raises the limits to 30 templates, unlimited exports, 100 test emails per day, 10GB of images, and 40 live client previews per month. Pro costs $79 per month with annual billing and includes 200 templates, unlimited exports, 500 test emails per day, 100GB of images, 150 live client previews per month, and priority support. Enterprise adds unlimited templates, exports, and test emails per day, plus API and integrations, custom live-preview limits, and priority support. The pricing page states that yearly billing provides two months free.

Postdrop’s strongest fit is template production and rendering review rather than broad email quality assurance. Its integrations include Mailchimp, Klaviyo, HubSpot, SendGrid, Customer.io, and OneSignal, while AI-assisted composition, brand settings, and team sharing support collaborative workflows. The product does not include verified spam, accessibility, or link-check features, so teams needing those checks should add another tool or choose an alternative with that coverage. Choose Postdrop for browser-based editing, client previews, inbox testing, and export; look elsewhere if API access is required below Enterprise or if compliance-oriented email validation is central.
