Omnisend segments are directly visible in Chatarmin and usable as WhatsApp target groups. No CSV export needed.
All Omnisend segments: VIP customers, cart abandoners, first-time buyers, email non-openers, custom segments. Import runs automatically after connecting the API key. New segments in Omnisend automatically appear in Chatarmin. You simply select the Omnisend segment as a target group for your WhatsApp campaign.
Omnisend workflows trigger WhatsApp flows and vice versa. Bidirectional and in real time.
Omnisend automation "Cart Abandoned" triggers an email after 1 hour. If the email is not opened, Chatarmin triggers a WhatsApp follow-up after 24 hours. The flows work together without overlapping. Data like open rates and clicks flow back into both systems.

Any e-commerce shop using Omnisend as their email/SMS tool that wants to add WhatsApp as a third direct channel. Three profiles come up most frequently in our conversations:
Omnisend has its own SMS feature. WhatsApp via Chatarmin complements SMS but does not replace it. In the DACH region, WhatsApp with 85% open rate is the stronger channel compared to SMS.
Omnisend shows you who did not open the newsletter. Chatarmin sends a WhatsApp follow-up to exactly this segment. 85% open rate instead of 0%.
VIP customers, cart abandoners, first-time buyers. Every Omnisend segment becomes a WhatsApp target group. No manual export.
Collect emails in WhatsApp flows and sync to Omnisend. Generate WhatsApp opt-ins in newsletters. Both channels grow simultaneously.
The biggest lever of the integration: three channels working together. Omnisend handles email and SMS. Chatarmin handles WhatsApp. Contact data flows bidirectionally.
Here is how it looks in practice:
Flow synchronization also works bidirectionally: Omnisend workflows can trigger WhatsApp flows and vice versa. "We can build in the automations you build in OmniSend, it's very similar" is how a Chatarmin founder describes it in a sales call.
As with all email integrations: WhatsApp and email do not cannibalize each other. In the WhatsApp welcome flow you collect the email address and sync it to Omnisend. In the Omnisend newsletter you place a WhatsApp opt-in link.
Contacts on multiple channels generate on average 2 to 3x more revenue than contacts on just one channel. After 3 to 6 months you build significant cross-channel overlap.

The connection between Omnisend and Chatarmin incurs no additional integration costs. You need an active Omnisend account and a Chatarmin account.
For WhatsApp messages, Meta charges 11 cents per marketing message in Germany. In Austria and Switzerland it is around 5 cents (as of 2026). Service messages within a 24-hour window are free.
11 cents per message sounds like a lot at first. But WhatsApp messages generate 2 to 3x higher revenue per recipient than emails. Assume you generate 1 EUR revenue per recipient via email, then you will land at around 2.50 EUR via WhatsApp. Minus 11 cents in Meta fees, you still have 139% higher net margin per contact than via email. That is why over 450 e-commerce brands successfully run WhatsApp marketing with Chatarmin.
