Amazon SES customers by country
Based on country-code domains (such as .de or .co.uk); websites on .com and other generic domains are not assigned a country.
TechLeads scans public websites and detects Amazon SES from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Amazon SES's website count divided by the website counts of all Email technologies we track; a site using two Email tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
