Messaging program
Last updated: August 30, 2026
1. Who sends these, and who receives one
The sender is a general contractor using Sealinn to keep track of subcontractor documents. The recipient is a subcontractor that contractor has hired or is hiring. The contractor may put a number on the record, but Sealinn does not text it until an opt-in for that exact number is submitted through the subcontractor record’s upload page.
You will never receive a text from Sealinn because you visited this website, filled in a form, or appear in a list somebody bought. There is no marketing list, and nothing on this site subscribes you to anything.
2. How you opt in
You do not need a Sealinn account. After opening the contractor’s upload page, you can enter a mobile number and press Text me reminders. Before you press it, the page identifies Sealinn and the contractor, describes the messages and frequency, states that message and data rates may apply, and explains STOP and HELP. The choice is optional and is not required to upload a document or work with the contractor.
We record when that choice was made, that it came from the subcontractor upload page, and the number it covered. The contractor-facing app has no consent control. The upload page uses a bearer link for a specific subcontractor record; it does not independently verify the submitter’s identity or ownership of the number. If the number on the record changes, the old consent does not move to the new number. You can turn texts off on the same upload page or reply STOP. Contractors must also follow our Acceptable Use Policy and use Sealinn only with people they actually work with or are actively engaging.
3. How many, and when
When the contractor has switched SMS reminders on, Sealinn can send a text at each day in that workspace’s reminder schedule. A contractor can choose up to six reminders before an expiry, and Sealinn may send follow-ups one, seven, and fourteen days after a document lapses. These scheduled texts are sent only while your number still has current consent.
A staff member can also send a renewal reminder from your record or include a text when rejecting a document, so those messages are additional to the schedule. The program is for renewal reminders and rejection notices—not advertising. Message and data rates may apply. Texting is available only on the contractor’s Growth plan and above, and the workspace can turn it off.
4. Stopping them, and getting help
Reply STOP to any message. It takes effect immediately, it does not need the contractor’s cooperation, and you do not have to find us first — the words are on every message we send. Reply HELP and you get back who we are, how to stop, and an address you can write to.
You can also use turn it off here on the upload page where you opted in. A STOP is honored across every workspace on Sealinn, not only the contractor whose message you replied to. From your side there is one sender, so an opt-out that only silenced one customer would not be an opt-out. That record outlives the workspace that prompted it, which is the one thing we keep specifically so we can keep leaving you alone — /privacy says so in the retention section.
Email works the same way by a different route: every email carries a working unsubscribe link, and using it has the same global effect.
5. Exactly what a message looks like
These are the three forms an outbound text takes. The contractor’s company name is always first, so you can tell at a glance who is asking:
- Apex Construction — the general liability entry on the certificate we have has a recorded expiry date in 30 days. Upload:https://sealinn.com/portal/… Reply STOP to opt out.A scheduled reminder before expiry.
- Apex Construction — the general liability entry on the certificate we have needs an updated document. Upload:https://sealinn.com/portal/… Reply STOP to opt out.A renewal reminder a person at the contractor sends from your record, and the wording used for scheduled follow-ups after a document lapses.
- Apex Construction — your Certificate of Insurance was rejected: limits below the required minimum. Re-upload: https://sealinn.com/portal/… Reply STOP to opt out.A document you already sent did not meet the contractor’s requirement, with a fresh link so you do not have to ask for one.
Every link goes to the upload page for a specific subcontractor record. It is a bearer link, so anyone who receives it can open it. There is nothing to install, no account to make, and no password.
6. What we hold, and for how long
The contractor may have entered the first number on your record. When you opt in, you confirm or replace it and we store the time, source, and exact number covered by that choice. The contractor can correct or delete the contact number in their workspace, but the contractor-facing app cannot grant consent for a replacement number. The same bearer link limitation described above still applies. Our Privacy Policy covers the rest: what is collected, why, and the window on each thing we keep. The Terms govern the contractor’s use of the product, not yours.
If you want to know what a specific contractor holds about you, ask them first — they are the ones who put it there. If you cannot reach them, privacy@sealinn.com is the alternate contact route for a privacy request; the contractor remains the party that decides what is held in its workspace.
