Messaging program
Last updated: August 1, 2026
1. Who sends these, and who receives one
The sender is a general contractor using Sealinn to keep track of their subcontractors’ insurance. The recipient is a subcontractor that contractor has hired or is hiring. We are the software in between — the message is theirs, and the phone number it goes to is one they entered.
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. What stands in for consent, stated plainly
Sealinn does not collect your consent, and we are not going to pretend otherwise. You have no account with us and no reason to have one. What makes a message to you legitimate is the working relationship you already have with the contractor who sent it — the same relationship that means they have your number in the first place.
Contractors agree, in our Acceptable Use Policy, to use this only for people they actually work with or are actively engaging. That is a rule we enforce by shutting off accounts, not a box a recipient ever ticked. If you are getting messages from a contractor you have no dealings with, tell us at privacy@sealinn.com and we will stop them regardless of what that contractor thinks.
3. How many, and when
Texts are not on a schedule. The automatic renewal reminders go by email. A text is sent only when a person at the contractor presses Text on your record, or when they reject a document you sent and choose to text you the re-upload link instead of emailing it.
In practice that means a handful a year at most, clustered around a certificate that is expiring or one that came back wrong. Message and data rates may apply. Texting is available only on the contractor’s Growth plan and above, so most workspaces send none at all.
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.
A STOP is honoured 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 two messages the product can send, rendered from the same code that sends them. The contractor’s company name is always first, so you can tell at a glance who is asking:
- Apex Construction — your general liability expires in 30 days. Upload:https://sealinn.com/portal/… Reply STOP to opt out.A renewal a person on the contractor’s side asked us to send.
- 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 an upload page for you specifically. There is nothing to install, no account to make, and no password.
6. What we hold, and for how long
Your number came from the contractor, and it is theirs to correct or delete — the tools to do that are in their workspace. 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 that goes nowhere, write to privacy@sealinn.com and we will help.
