When starting a business, should you use a free Gmail address or invest in custom domain email? ## Credibility A custom domain email ([email protected]) looks far more professional than [email protected]. Studies show that 75% of consumers trust custom domain emails more. ## Deliverability Custom domain email with proper SPF, DKIM, and DMARC authentication has significantly better inbox placement than shared free email services. ## Control With custom domain email, you own your address forever. If Google changes their terms or raises prices, you're not locked in. ## Cost ByteSMTP offers custom domain email starting at just $4.99/month for unlimited mailboxes. The ROI from improved credibility alone makes it worthwhile. ## The Verdict For any serious business, custom domain email is essential. It's affordable, more professional, and you maintain full control.
