Mujer Financiera +90% in email capture rate with a retirement calculator.

We turned a concern shared by its audience, how to prepare for retirement, into a useful tool for understanding their situation. We connected the calculator with content and emails based on age, goals and needs. An A/B test helped select the variant with a capture rate 90% higher than the other.

Early results

A useful tool and a conversion decision tested with data

Between September 30 and October 15, 2026, 457 people submitted their email. Of those, 293 were aged 50 or over, and 215 selected starting to invest as their main need. That information lets Sabrina and her team continue the relationship according to each person’s stage and interest.

In a randomized test, the variant asking for details before showing the result captured 298 emails from 925 visits: a 32.2% rate. The variant showing the number first captured 159 from 939 visits: 16.9%. The difference is 15.3 percentage points, equivalent to a 90% higher contact-capture rate, rounded to the nearest whole number.

The challenge

Reaching women thinking about retirement

Debt-related content attracted interest, but Sabrina wanted to prioritize women with capital and an interest in investing, especially those thinking about retirement. The team needed to learn who was responding and continue the relationship.

The decisions behind the case

A useful resource that helps understand the prospective student

The decisions behind this case.

  1. Content

    Talking about retirement to the intended audience

    The campaign revisited retirement questions the community was already asking. Each post invites a keyword comment to receive the calculator on Mujer Financiera’s own domain.

  2. Web and conversion

    The calculation provides context for a conversation

    The person provides their name, age, email and the area where they need help. They receive their plan by email and can continue to the investment pack. Follow-up messages use the information they shared.

  3. CRM

    Checking whether contacts match the intended audience

    Sabrina and her team can review each contact’s age, financial goal, starting capital and source in the CRM. This supports audience-fit assessment and personalized follow-up.
