Read the full review →Why MailStack
Built for UK stores, not US audiences
Every email marketing comparison site out there was built for a US audience. They show USD prices, ignore the GDPR question, and rank tools by commission rate rather than by what works for UK businesses.
MailStack exists to fix that. Every review shows GBP pricing with a clear note on currency conversion. Every tool is assessed against UK GDPR — specifically data residency and DPA availability. Every recommendation is made based on what works for UK Shopify stores.
