E-signatures, signed in the same link where they read them.

Collect legally binding, ESIGN- and eIDAS-compliant signatures right inside the thread. No redirect to a separate tool, no client account, no per-envelope fee; clients read the proposal and sign it in one place.

In short

Signing happens where the reading happens.

EverBird e-signatures live within the thread, so your client can read the proposal or contract and sign it at the same link, with no separate envelope, no account, and no redirect. Every signature is ESIGN-, UETA-, and eIDAS-compliant, sealed into a tamper-evident audit trail and certificate the moment the last field is signed.

Legally binding under ESIGN, UETA, and eIDAS.
Clients sign in the thread with no account or redirect.
Unlimited signatures, with an audit trail on every tier.

"Every redirect to a signing tool is a place the deal can stall. When the signature lives in the same link as the proposal, the client reads, signs, and you get the paperwork done before the enthusiasm cools."

How do I request a signature?

Drop signature fields on the doc.

Add signature, date, and initial fields to any document in the thread, or use a template where they’re already placed. Assign each field to a signer, and you’re ready to send.

What does the client do?

They open the link and sign.

No account, no redirect. Your client reads the document in the thread and types or draws their signature right where the field sits, on desktop or phone.

Is it actually binding?

Sealed with a full audit trail.

The moment the last field is signed, EverBird locks the document and generates an ESIGN, UETA, and eIDAS compliant certificate, signer identity, IP, timestamps, and document hash included.

What happens next?

Signed flows straight to paid.

The countersigned PDF and certificate file go back into the thread, and because signing lives alongside invoicing, you can send the first invoice the moment the ink dries, moving the deal straight to revenue with one link.

What's included

What e-signatures give you.

ESIGN, UETA & eIDAS compliant
Signatures are legally binding across the US and EU, so intent and consent are captured in context.
Type, draw, or upload
Signers choose a typed cursive signature, draw one by hand, or upload an image, on any device.
No account for signers
Clients open the same thread link and sign in place, with no login, no app, and no signup wall.
Multiple signers & order
Add co-founders, spouses, or witnesses and set a signing order. EverBird routes each in turn.
Tamper-evident audit trail
Every event, IP, timestamp, and document hash is sealed into a certificate you can download as a PDF.
Reusable signature fields
Save signature, date, and initial fields on your templates so contracts are sign-ready every time.
The agent chases unsigned docs
EverBird spots who is holding an unsigned proposal and drafts the follow-up in your voice.
Signed, chased & invoiced in one
Signature, follow-up, and invoice all happen on the same thread, from one link.

Agency business

A contract left unsigned is revenue you have already won but cannot recognize. Send it to a separate signing tool, and you add a redirect, a login, and a day of delay per handoff. Signing inside the thread means the client reads the proposal and signs in the same sitting, and the deposit invoice goes live the moment they do so so that revenue can be recognized sooner.

Service business

You cannot start work or issue an invoice until the NDA and the contract are returned. Both sit on one link the client signs from their phone, with no account to create, so the paperwork stops being what delays your start date and your first payment.

FAQ · E-signatures

E-signature questions.

Yes. EverBird e-signatures comply with the U.S. ESIGN Act and UETA, as well as the EU eIDAS regulation. Every signature captures the signer’s name, email, timestamp, and IP address, sealed into a tamper-evident audit trail and completion certificate that stands as evidence of intent to sign.
No. Your client opens the same thread link, reads the document, and signs in place, no login, no app, and no redirect to a separate signing tool. They type or draw their signature, and it’s done.
Each completed signature produces a certificate recording every signer, their email and IP address, the exact time each field was signed, the document version and its hash, and every view leading up to signing. It’s available for download as a PDF and attached to the thread. Signing events also flow into document tracking.
Yes. Add as many signers as a document needs- co-founders, spouses, witnesses- and set the order in which they sign. EverBird routes the request to each party in turn and notifies you as each signs.
No. E-signatures are unlimited across all tiers, with no per-envelope, per-seat, or per-signature charges. Pricing is in three flat-per-team tiers: Solo $39, Pro $129, and Max $349 per month. See pricing.

This runs on an agent, not a reminder timer.

Every thread sits under a Revenue Agent that reads the actual blocker, decides when to chase, sends from your own address and hands the deal back after three tries. There are three, and your plan decides how many you get.
