Full Provider Data
All providers with promo-to-renewal pricing, ranked by markup percentage.
Methodology
Hosting & Domains: Renewal Shock % is calculated as
((renewal − promo) / promo) × 100.
We use each host's featured plan and each registrar's .com pricing.
Email Marketing: Email tools use volume-based pricing (cost scales with subscribers), not promo-to-renewal. We show cost at each subscriber tier instead of a simple markup percentage.
All prices are verified monthly through direct checkout testing and published pricing pages.
