Everything your "marketing" team needs

Resolved in one exchange

A subscription change happens inside the conversation instead of the agent having to explain how to find the unsubscribe link or forward the request to marketing.

Reduces compliance risk

Consent is updated the moment the customer asks, giving you an accurate, timestamped record instead of a delayed batch update that leaves you sending to someone who already opted out.

Protects sender reputation

Prompt, accurate suppression handling keeps unwanted sends down, which matters directly for inbox placement and deliverability across your whole Klaviyo list.

No handoff to marketing ops

Support can action the request itself in real time, rather than logging a ticket for someone else to process later in the week.

Fewer repeat contacts

Because the change is confirmed immediately, customers are not messaging again days later to check whether their unsubscribe actually went through.

Recovers customers who opt back in

When someone changes their mind, resubscribing them on the spot means they do not miss the next campaign while waiting for a manual fix.
