§ 03Deep dive6 sections · honest take

The full picture, no fluff.

Long-form prose for the developer who wants the substance behind the table — what each platform is actually good at, and what they're not.

§ 01

Short answer: which one should you pick?

Mailform is the right call if you specifically need to mail a printed letter or generate a signed PDF from a form submission — it's one of the few backends with a real postal-delivery integration. If your workflow ends in 'this needs to arrive on paper at a physical address', Mailform earns the slot.

splitforms is the right call for everything else. If 'a user filled out a form' should result in storage, spam classification, webhook fan-out, and an inbox notification — without paying for postal infrastructure you'll never use — splitforms is leaner and cheaper at every volume tier.

§ 02

Why developers switch from Mailform to splitforms

The most common trigger is realizing the postal-mail and PDF features were never actually used. Mailform's pricing reflects those features whether or not you use them — pay-as-you-go fees and tiered plans tuned to physical-mail volume. splitforms is priced purely on submission volume with no per-event surprises.

The second trigger is the dashboard. Mailform's UI is tuned for the compliance/government-vendor buyer, which makes it heavier than developers usually want. splitforms ships a fast, search-and-filter-first dashboard that's faster to inspect submissions in.

The third trigger is webhooks and API surface. Mailform has webhooks, but the API and developer documentation are thinner than a developer-first product. splitforms ships an open REST API, signed webhooks with retries, and an MCP server on every plan.

§ 03

Mailform vs splitforms: feature comparison

Postal mail: Mailform yes, splitforms no. If you need this, Mailform wins.

PDF generation: Mailform yes, splitforms no (use a separate PDF service like DocRaptor + a webhook).

Storage: both store submissions; splitforms's search and filter is faster.

Spam protection: splitforms uses AI classification plus honeypot. Mailform uses CAPTCHA.

Pricing model: splitforms tiers on submission volume only. Mailform tiers on event types (email vs PDF vs postal).

API: splitforms ships a documented open REST API and MCP server. Mailform's API is less developer-focused.

Free tier: splitforms 1,000 submissions/month. Mailform free is low-volume email only.

§ 04

Common Mailform issues splitforms solves

"I'm paying for postal-mail features I never use." splitforms has flat per-submission pricing and no per-event upcharges.

"The dashboard feels heavy." splitforms is built for fast inspection: search, filter, export, re-deliver.

"I want signed webhooks with retries." splitforms includes them on every plan.

§ 05

How to migrate from Mailform to splitforms

If you don't use the postal-mail or PDF features, migration is the standard action-URL swap — change your form's action to `https://splitforms.com/api/submit` and you're done. If you do use those features, keep Mailform for the specific workflows that need them and route everything else to splitforms.

§ 06

  <button type="submit">Send</button>
</form>
STEP 03DEPLOY

§ 07Questions7 answered

Things developers ask before they switch.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Is splitforms actually a viable Mailform alternative?
Yes. splitforms covers the same core jobs as Mailform — POST endpoint, email delivery, dashboard, webhooks, spam filtering — at a lower price point with a larger free tier (1,000 submissions/month vs Free for low-volume email forwarding; PDF and physical mail are paid). Migration is a one-line change to your form's action URL.
02How long does it take to migrate from Mailform?
For a typical site with one to five forms, migration takes about 10 minutes: sign up at splitforms.com, get an access key, swap the action URL on each form, deploy, and submit a test entry. No SDK changes are required for vanilla HTML forms.
03Does splitforms support the same features as Mailform?
splitforms supports email delivery, a real submission dashboard with search and export, webhook delivery with retries, Storage-backed file uploads, CC/BCC recipients, custom redirect URLs, AI spam classification on top of honeypot, and a documented REST API. Specific Mailform features like can mail a printed letter from a form submission (postal upsell) may require a webhook integration on splitforms.
04What does splitforms cost compared to Mailform?
splitforms is free for 1,000 submissions/month, $5/mo for 5,000 submissions, and $59 once for 15,000 submissions/month over 48 months on the 4-Year plan. Mailform starts at Pay-as-you-go for PDF/postal; recurring plans for higher email volume. For most use cases, splitforms is meaningfully cheaper at the same submission volume.
05Will my existing Mailform forms break if I switch?
No. The HTML form itself doesn't change — only the action attribute. Existing field names, validation, and styling all work identically. The only practical change is where the POST goes.
06Does splitforms have a one-time payment plan?
Yes — the 4-Year plan is $59 once for 48 months of access at 15,000 submissions/month, with no recurring billing during that span. Mailform does not currently offer a one-time payment option.
07Is splitforms a good fit for workflows that need a physical mailing or signed pdf, not just an email.?
splitforms is built for developers shipping production sites — static sites, SaaS landing pages, JAMstack apps, agency client work. If your specific need is workflows that need a physical mailing or signed pdf, not just an email., evaluate whether can mail a printed letter from a form submission (postal upsell) is decisive for you. If not, splitforms is likely the better economic and technical fit.
