DeepL Glossary Leverage

DeepL's Growth plan includes 2,000 glossaries, a feature that agencies can turn into a retention engine. Each glossary enforces brand terminology across 100+ languages, so a retail client's product names and tone stay consistent in every market. Instead of selling one-off translations, an agency can set up a glossary per client and then use DeepL's API to embed translation into the client's content pipeline. For example, an agency serving an e-commerce brand with 50 product categories can create a glossary for each category, ensuring that 'sneaker' never becomes 'trainer' in UK English. The $26/month Growth plan covers 12 million characters per year, which is roughly 18,000 pages of translated copy, enough to support several retainers. By tying the glossary setup to a monthly retainer, the agency creates a recurring revenue stream that is hard to replicate with generic machine translation tools.
