Create Additional Renewal Notification Emails

Overview

As part of improving the overall renewal process, we want to add some new renewal notification emails with additional context. The content and overview can be found in this issue: https://gitlab.com/gitlab-com/marketing/digital-marketing-programs/issues/1446

We currently only send one renewal notification to customers 30 days before their renewal. Some customers require more advanced notice. This change adds multiple notifications over a 90-day window with customized instructions that are specific to the customer and their subscription.

The goal of this effort is to give customers more advanced warning, multiple touchpoints, and clearer directions.

Next Steps:

• Review edits to emails
• Review with stakeholders
• Create emails on staging
• Test on staging
• Create on production
