What is consented to receive SMS?

Consented to receive SMS is a metric for when someone gives their explicit consent to receive SMS messages from your brand. Tracking this metric helps make sure you only send messages to subscribers who have opted in, which is key for staying compliant with SMS marketing regulations.

5 ways to collect SMS consent

You need to get express consent from your audience before sending them any type of SMS message, whether promotional or conversational. The only exception is for conversational messages, where consent is implied when the customer initiates the conversation.

Here’s how you can obtain consent before sending text messages to your audience:

1. Use sign-up forms

Sign-up forms are one of the most effective ways to get SMS consent. When you use a single opt-in in Klaviyo’s sign-up forms, all visitors who enter their phone numbers automatically give you their consent to receive marketing messages via text.

You can also use a double opt-in, where visitors have to confirm their choice after giving you their phone number. While this is not a regulatory requirement in the US, double opt-in ensures that your SMS messages are sent to people genuinely interested in your brand.

2. Reach out to email subscribers

To comply with SMS regulations, you must collect SMS consent independently from your other marketing channels. Having someone’s consent to send them emails doesn’t mean you can send them SMS messages, too.

Launch a new email campaign to encourage your current subscribers to join your SMS marketing channel. Email your most engaged segments first to maximize your success.

3. Use a check box or an automated flow at check-out

Another efficient way to grow your SMS list is to include an opt-in checkbox at the end of the check-out process or use a post-purchase automated flow

Visitors who have bought products from your brand are already interested, so this is a great opportunity to invite them to join your SMS list.

4. Use social media

Promote your SMS marketing channel on social networks like TikTok or Instagram. Use the networks with the largest follower base to your advantage by asking your followers to sign up for your SMS updates, too.

5. Run promotions

You can display an advertisement containing a short code or a toll-free number and a keyword that your audience can use to opt into your SMS marketing campaigns.

Give your visitors a compelling reason to join by offering a hefty discount or early access to a new product you’re preparing to launch.

6. Use a marketing automation platform
