Imagine remarketing that costs $20, not a media budget.
Set a $20 budget and a goal. Zellwo writes to the people who already know you, by email, SMS or newsletter, natively in each contact's language, within your caps and quiet hours, with a holdout group set aside. Every reply gets an answer from your support agent, and the page shows what each purchase cost.

Answer and count
Every reply becomes a ticket the same agent answers. Results count orders and replies, not opens.
Outreach
Start from an email address. Zellwo does the homework.
Type an address and Zellwo finds or creates the contact and the company, researches both on the web, checks the VAT number and writes a first message that shows you know who you are writing to. When nobody answers, it decides whether to follow up.

Hi Erik, congrats on the new Borås warehouse. When it ships to Norway, we can take the cross-border leg.

A holdout groupPart of the segment is set aside and never mailed, so the campaign is told apart from orders that came anyway.

FAQs
What does Zellwo Marketing actually do?
It builds segments from what your customers did and how often they buy, writes email, SMS and newsletter campaigns in every language you tick, sends them within your limits with a holdout group, and answers every reply with the agent that runs your support.
Do I still need Klaviyo or Omnisend?
No. Campaigns, newsletters, SMS, segments and support share one customer record: nothing to sync, no reply lost in a no-reply box.
Templates or AI-written emails?
Both. Templates with merge fields for newsletters and SMS, or AI-personalised emails that use the contact's research profile, from the opening line to the whole message. The first 20 AI emails wait for your approval.
Will it spam my customers?
It works within your rules: daily and budget caps, a maximum per contact and quiet hours in each contact's own timezone. Every email carries a one-click unsubscribe, and a campaign pauses itself when bounces or unsubscribes climb.
How is this cheaper than Facebook or Google remarketing?
You pay for the email and the SMS, cents each, to people who already gave you their address, instead of bidding per click to reach them again. The campaign page shows spend and cost per acquisition, and the holdout group shows what the spend bought.
