Your sales ops team maintains 40+ email templates. Every time the CEO's signature changes or you rename a product line, you hunt through dozens of templates fixing the same Qweb expression over and over. One typo in a customer-facing email costs credibility. This addon lets you define custom variables once—company tagline, support phone, promo disclaimers, calculated fields—then drop them into any template with a simple placeholder. Change the variable definition in one place and every template updates instantly. No more grep-and-replace across your template library. Sales ops at a 200-person distributor reported cutting template maintenance from 3 hours per week to under 20 minutes. Define your variables once and forget them.
