What is an Email Sending Domain?

An email sending domain is a domain that you own and configure to send emails from your email marketing campaigns. It serves as the “From” address domain for your emails (e.g., if you send from newsletter@yourdomain.com, then yourdomain.com is your email sending domain).

​
Why Use Email Sending Domains?

  • Improved Deliverability: ISPs trust emails from verified domains more than generic sending services
  • Brand Recognition: Recipients see emails coming from your branded domain
  • Authentication: Enables proper SPF, DKIM, and DMARC authentication
  • Reputation Building: Builds sender reputation tied to your domain rather than a shared service

​
Domain Verification Process

Before you can send emails from a domain, it must be verified through DNS records to prove ownership and enable proper email authentication. Simpu provides APIs to register and manage sending domains via the hooks defined below.

​
useGetEmailDomains

The useGetEmailDomains hook fetches email domains, allowing you to retrieve a list of domains and their details. API Reference

    return <div>Loading...</div>;
  }

  if (isError) {
    return <div>Error loading sending domains</div>;
  }

  return (
    <div>
      {data.map((domain) => (
        <div key={domain.id}>
          <h3>{domain.domain}</h3>
          <p>Status: {domain.status}</p>
        </div>
      ))}
