May is a packed release: approval workflows before signing, fuller envelopes, batch sends, safer API testing, and a long list of improvements to the signing experience, the dashboard, and developer tooling.
Here is what is new.
Envelope approvers
You can now add approvers to an envelope. After you send, the envelope enters an approving phase first: approvers review the document and approve or decline. Only when every approver has approved do signers receive their invitations.
Useful when legal, a manager, or compliance needs to validate a contract before it goes to the customer. Approvers and signers are managed separately in the editor; you can reorder approvers the same way as signers.
Learn more: Adding recipients (approvers, signers, and signing order).
Multiple signable documents in one envelope
You can add more than one document that must be signed inside a single envelope. Send a contract with its annexes, an onboarding pack, or a full dossier in one request. Signers open one link and complete everything in one flow instead of juggling separate emails.
This is available on paid plans (up to 50 signable documents per envelope). While preparing a draft, use Add document in the envelope editor to upload another PDF or Word file and place fields on each document.
Learn more: Envelope structure.
Bulk send from a template
When the same template goes to many people and your internal signers stay the same, bulk send saves repetitive work. Pick fixed recipients once (for example your sales rep), choose which template role changes on each send (for example the customer), then build a list from your contact book or a CSV file. Subnoto creates and sends one envelope per row, with progress for each line.
Typical uses: NDAs to a client list, mandate renewals, or standard agreements where only the external party changes. Up to 100 recipients per batch on Pro and Ultimate plans.

API sandbox workspaces
Integrating Subnoto into your product or back office? Sandbox mode lets you run the full workflow without production side effects: no invitation emails, no credit usage, and test signatures instead of production certificates. Enable it on a dedicated workspace via the public API, exercise webhooks and signing flows, then turn sandbox off before going live.

Audit proof and signed PDFs in completion emails
When every signer has finished, Subnoto sends a completion email with a secure link to the envelope. Team administrators can also attach files to those emails: the audit proof PDF (on by default) and, if you opt in, the final signed documents. Handy when someone needs an immediate copy in their inbox for filing, without opening the app first.
The proof is always generated and stored in Subnoto when an envelope completes. The settings only control what is attached to the email.

Sign in person
Sometimes a signer is with you on site but cannot use the signing link on their own device. From the envelope view, choose Options → Sign in person next to their name. You complete fields and capture their signature on your device; they confirm identity with a verification code sent by email or SMS. The audit trail records that verification was done in person.
In-person signing is available while the envelope is in progress, for eligible signers, and not in sandbox workspaces.

More updates
A few more changes that did not each need their own headline, but matter day to day:
- Signer experience - We reworked the signing flow with a strong focus on mobile: clearer steps, easier navigation on a phone, and a smoother path from invitation to done.
- Fillable fields - Input fields on documents (text, checkboxes, dropdowns, and more) are easier to use for signers and more reliable while filling.
- Go SDK - We are adding Go to our official SDK lineup alongside TypeScript, Python, and PHP. See the SDK overview to get started.
- Signature watermark - On plans with custom team branding, administrators can turn off the Subnoto trust seal behind visible signatures when you prefer a cleaner PDF. See Signature watermark settings (email logo and colors are configured in the same Customization section).
- Dashboard - The home dashboard has a new design to surface what needs your attention faster.
- Date field block - A dedicated date block is available when placing fields on a document. See Placing signature fields.
- Email customization - More options to tailor invitation and notification emails (messages, branding, and related settings where your plan allows it).
- Extend expiration - For expired envelopes, you can extend the deadline from the app instead of only duplicating the envelope. See Envelope expiration for how deadlines work.
We also fixed a lot of smaller issues reported through support and in-app feedback. Thank you to everyone who took the time to tell us what was broken or confusing - it genuinely helps us prioritize.
Every signature processed through Subnoto stays private and secure. Documents remain encrypted at all times, even during processing.
