SMS invites deliver your signing link straight to a recipient’s phone, cutting through crowded inboxes and speeding turnarounds—especially for contractors, field staff, patients, and customers who live on mobile. Use it when you don’t have a reliable email, when emails bounce, or when you need a fast, day-of signature (deliveries, check-ins, work orders, consents).
For best results, include your company name and a short purpose in the invite message to build trust (“Acme—NDA for today’s call”). Set a realistic expiration and reminders to keep momentum, and verify phone numbers (country code included) before sending. If your policy requires an email record, send both SMS and email; the signing experience is the same, and all actions remain audit-ready.
Signers will receive a text message from the following Twilio numbers: +18885575977, +1888*****97, or +1888557XXXX.
SMS invite can be sent to multiple signers via the same phone number. If the document needs to be signed by different individuals using the same mobile number, they will receive a text message with different links to open the document so that they can sign their own copy.
When you customize your invite on the Invite Page, click on the envelope icon near the recipient’s email address. In the dropdown, select SMS. The email address field will change to the phone number field.
