Summary
Selecting the right Top-Level Domain (TLD) is crucial for email deliverability. Several TLDs like .io, .xyz, .top, .tk, .ga, .cf, and .gq are frequently associated with spam or have a poor reputation due to abuse. These can trigger spam filters and negatively impact deliverability. While .org domains might face compliance issues, it is also important to research and monitor all TLDs' reputations before using them. Email providers and organizations such as Spamhaus, ICANN, Google, and Microsoft recommend using reputable domains, monitoring sending behavior, and maintaining a clean sending reputation to avoid deliverability issues. Content and sending practices remain crucial, regardless of the chosen TLD. Startups using non-.com TLDs may also face reputation challenges.
