The language at your opt-in point, the text on the form, the confirmation after a keyword, does double duty: it's the first impression that sets expectations, and it's the consent record you'll rely on if anyone asks. Getting it right is easy and cheap; getting it wrong quietly weakens every opt-in you collect. Here's what your opt-in language should include.
What should opt-in language include?
Clear, honest elements that leave no doubt what the person agreed to:
- Who's sending. Name the campaign, so the consent is tied to you specifically. See sender identification.
- What they'll get. "Campaign updates," "GOTV reminders", a plain description of the messages.
- That it's a text opt-in. Make explicit that they're agreeing to receive text messages.
- Frequency and rates. A note like "message frequency varies, message and data rates may apply."
- How to opt out. "Text STOP to unsubscribe, HELP for help."
Together these turn a vague signup into a documented, specific consent.
Why does clarity protect you?
Because a dispute turns on what the person agreed to, and clear language is the proof. Ambiguous or missing opt-in language leaves you arguing that consent was implied; specific language, naming you, describing the texts, noting opt-out, lets you show exactly what they agreed to and when. It's also a carrier expectation, standard opt-in disclosures (frequency, rates, STOP/HELP) are part of what the carriers look for, so clear language supports deliverability too. Good opt-in language is both a legal asset and a trust signal.
What about different opt-in methods?
Match the language to the method, but keep the elements. A web form can carry the full disclosure near the submit button. A keyword opt-in delivers it in the confirmation text ("You're subscribed to Campaign updates. Msg freq varies, msg&data rates may apply. Text STOP to end, HELP for help."). A QR code lands on a page with the disclosure. However someone opts in, the moment should capture clear language and a logged record of it.
Frequently asked questions
What should opt-in language say?
It should name the campaign, describe what messages they'll get, make clear it's a text opt-in, note that frequency varies and rates may apply, and explain how to opt out (STOP) and get help (HELP).
Why does opt-in language matter?
Because it's your consent record and your first impression. Clear language proves exactly what someone agreed to in a dispute, supports carrier deliverability expectations, and sets honest expectations that reduce opt-outs.
Does opt-in language differ by method?
The elements stay the same; the placement changes. A web form carries it near submit, a keyword opt-in delivers it in the confirmation text, a QR code lands on a page with the disclosure. Log the record in every case.
