JS2Mail vs Formspree, Web3Forms, Netlify Forms, Getform

Honest, vendor-by-vendor look. The biggest split: where the submission email comes from — your own mailbox, or a generic provider domain like [email protected].

When each one wins

Formspree
The classic, but submissions come from formspree.io

Formspree pioneered the action-URL pattern and has the most mature feature set: paid plans get spam filters, file uploads, autoresponders. The trade-off is the sender identity — the inbox sees mail from formspree.io and threading collapses, so replies don't land in the visitor's thread.

When to pick: Pick Formspree if you want a stable, mature provider and don't mind the sender address.
Web3Forms
Free, fast, ad-supported

Web3Forms is the most minimal of the bunch. Unlimited submissions on the free tier, no account required to send (just an access key). Mail comes from [email protected] and the free tier injects a small footer ad.

When to pick: Pick Web3Forms if you want zero setup and don't care about sender identity or branding.
Netlify Forms
Frictionless if you already host on Netlify

Adds a single attribute to your form (data-netlify="true") and Netlify takes over. No external account needed. Submissions land in the Netlify dashboard with email notifications. The catch: only works on Netlify-hosted sites, and you're capped at 100/mo unless you upgrade.

When to pick: Pick Netlify Forms if your site is already on Netlify and you accept their dashboard as the submission home.
Getform
Forms-with-integrations focus

Getform leans into the no-code integrations angle: Zapier, Mailchimp, Slack, Google Sheets out of the box. Sender identity is getform.io. Paid plans add custom email templates, file uploads, multiple endpoints.

When to pick: Pick Getform if you want submissions to flow into other SaaS tools more than into a mailbox.
JS2Mail
This one
Built for AI-generated sites

Submissions arrive from your own mailbox, so the visitor's reply threads into your inbox like any other email. The MCP server lets an AI assistant provision the endpoint without a single click from the user. Same API also powers transactional mail — confirmations, password resets, notifications.

When to pick: Pick JS2Mail if you want inbox-native ergonomics, AI-friendly provisioning, or one API for both forms and transactional mail.
