Marketing Opt-In After Signup

Last updated: June 10, 2026

When creators sign up through a Superfiliate application form, they may see an option such as "Receive marketing communications and updates."

This article explains what happens if a creator does not check that box during signup and how they can subscribe later.

What does the marketing opt-in checkbox do?

The marketing opt-in checkbox allows Superfiliate to pass a consent signal to the brand's connected marketing platforms, such as:

  • Klaviyo (Email)

  • Postscript (SMS)

  • Attentive (SMS)

If the creator checks the box during signup, they may be added to the brand's marketing audience according to the brand's configuration.

If they leave the box unchecked, Superfiliate will not pass marketing consent to those platforms.

Can a creator opt in later?

Yes.

However, creators cannot update their original application form submission to change their marketing consent status.

Instead, they must subscribe through the brand's normal email or SMS marketing channels.

Email subscriptions

Creators can subscribe through any of the brand's standard email signup methods, such as:

  • Website popups

  • Embedded newsletter forms

  • Footer signup forms

  • Klaviyo-hosted signup pages

Alternatively, the brand can manually add the creator to its email marketing platform and collect consent according to its own policies.

SMS subscriptions

Creators can subscribe through the brand's standard SMS opt-in methods, such as:

  • SMS keywords (for example, texting a keyword to the brand's SMS number)

  • Website SMS signup forms

  • Checkout SMS consent forms

The exact opt-in process depends on the brand's SMS provider and configuration.

Will they receive welcome emails or welcome SMS messages?

It depends on how the welcome message is configured.

Marketing-platform welcome flows

If the welcome email or SMS is sent through a marketing platform such as Klaviyo, Postscript, or Attentive, the creator typically must be subscribed on that channel before receiving those messages.

Superfiliate-native automations

If the welcome message is configured as a Superfiliate automation, it may still be delivered because it is treated as a transactional program communication rather than a marketing subscription message.

Key Takeaways

  • Creators can opt in to marketing after signup.

  • They cannot update the original Superfiliate application form to change their marketing consent.

  • Future marketing consent must be collected through the brand's normal email or SMS subscription channels.

  • Welcome flows sent through marketing platforms generally require an active subscription.

  • Superfiliate login codes are transactional and will still be delivered regardless of marketing opt-in status.
