Supported TLDs (Top-Level Domains)

A TLD (Top-Level Domain) is the last part of your domain name, for example .com, .io, or .co.uk.

When sending cold emails, your domain plays an important role in deliverability.
Choosing a reliable and widely trusted TLD can help improve inbox placement and reduce the chances of emails landing in spam.

Using .com domain is recommended, as it is the most trusted and widely accepted across email providers.
Extensions like .co and .org are also commonly used and perform well.

What are TLDs?

A Top-Level Domain (TLD) is the suffix at the end of a domain name. It can represent:

  • A type of organization such as .org or .edu
  • A country such as .in or .uk
  • A modern or custom extension such as .io or .tech

The following TLDs are considered lower-trust for cold email mainly because they are widely used for spam due to being cheap and easy to register:
.biz
.xyz
.me
.info
.site
.tech
.pro
.space

Disadvantages of having the low-level TLDs:

  • Higher chances of landing in spam
  • Lower trust with inbox providers like Gmail
  • Slower reputation building (needs longer warmup)
  • Lower open and reply rates
  • More sensitive to sending volume spikes
  • Higher chances of being flagged or temporarily blocked
  • Harder to recover reputation once flagged
