Best practices for collecting consent across channels
Customers encounter your brand across many channels, and each touchpoint plays a role in building your audience. Rather than relying on a single acquisition moment, effective strategies create opportunities to collect consent wherever engagement occurs. The best practices below outline practical approaches for capturing subscribers across digital and real-world interactions.
Use social media auto-replies to capture consent
Social interactions are often high-intent moments, making them strong opportunities to collect marketing consent. Auto-replies on Instagram, for example, allow you to turn comments and direct messages (DMs) into automated conversations that invite followers to opt in without leaving the platform. This helps convert engagement into measurable list growth while reducing friction.
- Trigger auto-replies when someone comments on a post or sends a DM. For example, if someone comments “enter” on a giveaway post, they can automatically receive a message inviting them to subscribe.
- Prompt followers to opt in to email or text messaging within the conversation. Instead of sending people to a sign-up form on your website, you can ask for their email or phone number directly in the chat flow.
- Add new subscribers to your lists so they can receive campaigns or flows right away. Once someone opts in, you can immediately include them in welcome messages. Start sending them campaign promotions and educational content to help them learn more about your brand.
Use lookalike audiences and lead ads to reach new subscribers
Paid social can help grow your audience beyond people who already know your brand. By syncing your existing lists and segments to ad platforms, you can create lookalike audiences that target people with similar behaviors or characteristics, making acquisition efforts more efficient.
- Sync high-value segments to ad platforms to build lookalike audiences. For example, you might sync a segment of repeat purchasers to create lookalike audiences in Instagram, TikTok, Google, Facebook, Pinterest, and Criteo that help you reach similar shoppers who are more likely to convert.
- Use lead ads to collect email or text message consent directly within social platforms. When someone completes a lead ad form on Facebook or Instagram, their information syncs to your marketing lists in real time, creating a frictionless acquisition flow.
- Align paid acquisition targeting with your lifecycle segments and growth goals. For instance, you could target unsubscribed profiles or recent site visitors with ads that encourage them to subscribe, then nurture them with campaigns after they opt in.
Use campaigns to grow subscribers across channels
Your existing marketing channels can help you grow other parts of your audience. By promoting app downloads, email sign-ups, or text messaging through campaigns, you can guide engaged subscribers to take the next step in how they interact with your brand. This helps strengthen cross-channel engagement and increases the likelihood that customers stay connected over time.
- Highlight the value of subscribing to additional channels. You might send an email campaign explaining that signing up for text messages means faster updates on limited-time offers or restocks. This can help build a sense of exclusivity and drive more sign-ups.
- Promote app downloads through email or text campaigns. For example, for text subscribers, send a message highlighting that mobile app users get early access to sales or exclusive product drops, adding even more value.
- Use time-sensitive messaging to encourage action. Use urgency in a campaign announcing an app-only sale. This will help motivate subscribers to download before the promotion begins.
Capture consent at checkout and post-purchase touchpoints
Moments like checkout and delivery are high-intent points where customers are already engaged with your brand. By collecting consent during or after a purchase, you can turn one-time buyers into long-term subscribers without interrupting the experience. These touchpoints help reinforce your value while making it easy to stay connected.
- Collect consent during online and in-store checkout. For example, include an option to sign up for email or text updates at checkout so customers can receive order updates, offers, or product recommendations.
- Use signage to promote subscription opportunities in physical spaces. You might display a QR code at the register or on packaging that invites customers to sign up for exclusive offers or updates.
- Extend consent collection into the delivery experience. For instance, include a card or insert in shipped orders encouraging customers to subscribe for future promotions, restock alerts, or loyalty perks.
