Every text comes from 1-866-907-SIGN — (866) 907-7446, a toll-free number verified with the carriers. One number, every message, so a recipient who does not recognise it can look it up and find this page.
SignSealer sends transactional messages only. A link to a document you have been asked to sign, one reminder if you have not, and a confirmation when everyone has. No marketing, no promotions, no newsletters — and not "not yet": the engine refuses to record consent for a marketing purpose, so it cannot send one by accident.
SignSealer sends on behalf of the business you are dealing with — the campground, the outfitter, the gym, the contractor. Their name is in the message. We are the platform they use to send it, in the same way an email provider is.
A link to a document the person has been asked to sign, sent because the business they are dealing with asked us to send it.
Harbour Rentals has asked you to sign "Rental agreement". https://sign.harbour.test/s/xxxx Reply STOP to opt out.
One reminder about a document already sent and not yet signed. Not a sequence: one.
Reminder: Harbour Rentals is still waiting on your signature for "Rental agreement". https://sign.harbour.test/s/xxxx Reply STOP to opt out.
Confirmation that everyone has signed, with the code the person can check the agreement by.
Everyone has now signed "Rental agreement". Check it any time with code ABCD-1234 at https://signsealer.com/verify Reply STOP to opt out.
By the business, not by us, at the point where they take your number — a booking form, a registration, the counter. They tell us the number, the purpose, where they obtained it and the exact wording you agreed to, and we record all four. A message cannot be sent to a number with no such record: the engine marks it suppressed and says why.
Typical wording, at a booking form:
Text me my paperwork. We will send a link to sign, one reminder, and a confirmation. Message and data rates may apply. Message frequency varies. Reply HELP for help, STOP to opt out.
Consent is recorded per purpose. Agreeing to receive the document is not agreeing to receive a reminder, and the engine treats those as separate records rather than as one checkbox — because under the TCPA they are separate questions.
Reply STOP to any message and it stops immediately. No confirmation step and no question: an unsubscribe that asks a question is an unsubscribe that does not work.
A STOP does two things, and the second is the one that matters: it suppresses the number, and it revokes every consent recorded against it. The business cannot record a new attestation to put you back — they are not the one who withdrew it. If you change your mind you opt in again yourself.
Reply HELP and you get a message saying who is texting you, what for, and how to reach a person: support@signsealer.com.
Message frequency varies and depends on how many documents you are sent. In practice it is one message per document, plus at most one reminder, plus one confirmation. Message and data rates may apply.
Consent is not shared with third parties or affiliates for marketing purposes. Your number is used to deliver the messages described above and for nothing else. It reaches our messaging carrier in order to be delivered, and no further — see our privacy policy and subprocessor list.
These obligations are mostly yours, and switching texting on means taking them on:
