You send a quote for a job worth several million. The address it comes from is construction.skopje.1985@gmail.com.
Nothing is technically wrong with that. But for the person reading it, something does not sit right.
What the address says
On your own domain: you have a company, you have a website, someone took care of it. You look like you will still exist next year.
On Gmail: you may be excellent, but there is no signal of it. And it looks like you are saving on the basics.
The practical differences
- The address is yours — if an employee leaves, it stays with you
- As many as you want — info, sales, accounts, one per department
- It does not land in spam — with proper SPF and DKIM records
- It looks the same everywhere — on invoices, business cards, the website
The most common misconception
"But I like using Gmail, it is easier." You can. An address on your own domain connects to Gmail or Outlook — you write from your address and use an interface you already know.
One thing many miss
If you send invoices or quotes and your email lands in spam, you do not know. The client thinks you never replied, you think they never answered.
That is usually because SPF, DKIM and DMARC are missing — three lines in the settings that tell the world you really send from that domain. With hosting on your own domain, that is set up once and it works. With free addresses, it does not exist at all.
