Form backend for agencies: one tool across every client site
Formspring collects, filters, routes, and retains every submission. Developers still get one endpoint, signed webhooks, API access, and the examples below.

What this workflow fixes
From paper-cut to plumbing.
Pain on the left, what changes on the right.
Lost or delayed submissions
Persistent inbox, signed webhooks, retries
Spam and low-quality responses
Honeypot + hCaptcha + AI moderation
Manual forwarding and copy-paste
Route to Slack, Sheets, Notion, CRM, webhook
Unsafe file attachments
Encrypted storage, time-limited signed links
Unclear GDPR retention
Per-form retention rule with auto-cleanup
Scattered inboxes and handoffs
One destination per team, audit trail
Agencies ship dozens of client sites a year, and every one of them needs a contact or lead form. Building intake plumbing per client - SMTP credentials, spam tuning, deliverability monitoring, dashboards - is the kind of work that does not scale. Formspring is the contact-form layer agencies plug into every static site, every WordPress build, every Shopify storefront. One workspace per client, agency members as admins, client members as viewers, all submissions routed to the right person on day one.
Technical implementation
<form action="https://formspring.io/f/abc123" method="POST">
<input name="name" required>
<input type="email" name="email" required>
<textarea name="message" required></textarea>
<button>Send</button>
</form>How it works
You sign up at Formspring, create a form, and copy its endpoint URL (https://formspring.io/f/abc123). Drop that URL into your <form action> attribute - that's the entire integration. Submissions go through five spam-protection layers and arrive in your dashboard within seconds. From there, notify the team, send data to Slack, Notion, Airtable, HubSpot, or Sheets, fire signed webhooks, or process via API.
Why this beats custom intake plumbing
A custom contact workflow means parsing form data, validating fields, handling spam, configuring SMTP, storing submissions, routing files, dealing with timeouts, debugging failures, and maintaining all of that. Formspring replaces the routine parts with one endpoint and keeps the technical escape hatches for teams that need them.
Security and privacy
Submissions are encrypted in transit and at rest. Files (if uploaded) sit in private S3-compatible storage and are only accessible via signed URLs from the dashboard. EU-only hosting in data centres in Germany and Finland. DPA included on every paid plan. Per-form retention rules let you auto-delete after N days for GDPR.
When to build it yourself
Three cases where custom intake is still right: (1) you already run the full workflow inside your application, (2) you need extreme low-latency processing (<10ms p99), or (3) compliance requires absolute zero data egress. For most website intake workflows, Formspring is the simpler answer.
