Zainith needed seven-figure e-commerce brands to say yes to one more agency email.

Zainith Agency runs TikTok Shop programs for e-commerce brands, with creators who promote the products and get paid on commission. Its buyers, the founders and marketing leads of seven-figure brands, get a constant stream of agency pitches about ad creative, email flows and ROAS.

The first two campaigns showed how hard that inbox is. They launched on eight openers that compared TikTok Shop with Meta on cost, attribution and reach, and together they drew 201 replies and only 6 interested leads.

The pitch was where the interest was dying. That's where we went to work.

What we built.

We changed the offer first, then read every segment on its own numbers.

    Brand lists built by industry and technology, then qualified one by one.

  3. Segmentation

    Every campaign split by vertical, company size and inbox provider.

  4. Offer

    A TikTok Shop playbook written for the brand.

  5. Messaging

    Two sentences and a question, signed by the founder.

  6. Iteration

    A new version every week, aimed at the next size band.

  7. Deliverability

From a brand list to a playbook request.

Every brand was qualified before it got an email, and every campaign was split so each result stood on its own. The email offered a TikTok Shop playbook in the founder's name and asked one question: mind if I send it over?
