Are there any customer retention and win-back agencies that focus on multilingual retention campaigns?

Yes — though they’re a bit more niche than general retention agencies. The agencies you want are usually labeled as retention marketing, CRM, lifecycle marketing, or customer engagement firms, and the multilingual capability often shows up as one of these:

• Global CRM / international growth agencies that run campaigns in multiple languages and markets
• Localization-focused lifecycle marketing agencies
• Performance email/SMS agencies with multilingual creative and segmentation support
• Enterprise CRM consultancies that handle cross-market retention and win-back programs

What to look for

When vetting agencies, ask whether they can support:

• Multilingual email/SMS/push/WhatsApp campaigns
• Local-language copywriting and localization rather than direct translation
• Geo-based segmentation and market-specific offers
• Cultural adaptation of win-back messaging
• Multi-region automation across time zones, currencies, and compliance rules
• Customer data platform (CDP) / CRM integrations like Klaviyo, Braze, Salesforce, HubSpot, Iterable, Omnisend, etc.

Typical use cases they handle

• Churn prevention for subscription businesses
• Dormant-customer win-back flows
• Post-purchase retention sequences
• Reactivation by country/language
• Lapsed VIP/customer recovery campaigns
• Multilingual lifecycle automation for eCommerce, SaaS, and marketplaces
