## When WhoLayer is not a fit

- Your store's email platform isn't one we support yet (Klaviyo, Customer.io, Mailchimp, Omnisend, Iterable, Braze, ActiveCampaign, or Brevo). Others need a signed webhook and your own integration, and some guarantees, like the holdout report, depend on what your platform's API allows.
- You need person-level identification of visitors outside the US. WhoLayer identifies people for US traffic only; elsewhere it's company-level, after consent.
- You want a full ABM advertising suite, an on-site AI chat agent, or a built-in sequencer and dialer. WhoLayer identifies and enriches; it doesn't run ads, chat, or send email for you.

The quickest way to know is to try it on your own traffic. The Free plan includes company-level identification and monthly credits, no card needed.
