Why your restaurant needs its own email domain
Sending from hello@yourrestaurant.com instead of a gmail address moves open rates more than any subject line trick.
If you send your reopening announcement from goldencrust@gmail.com, two things happen. The first is that gmail’s spam filter is more skeptical of your message than it would be of a domain it has seen before. The second is that a diner looking at their inbox on a Sunday evening does not immediately recognize you — it looks like a personal email, not a business.
Both of those are fixable with a real domain.
What "verified" means
When you send mail from hello@yourrestaurant.com, mail servers want three DNS records that cryptographically prove you are allowed to send on behalf of that domain: SPF, DKIM, DMARC. These records live with your DNS provider. Without them, you land in the promotions tab at best and the spam folder at worst.
Nordkestrel sets these up automatically during onboarding. You do not need to know what DKIM stands for — we write the record, you paste it into your DNS, we verify it works.
The open-rate bump
Restaurants we moved from a free Gmail-based list over to their own verified domain saw open rates climb 20–35% on the first send. Nothing else changed — same list, same subject line, same copy. The only difference was that inbox providers trusted the sender.
Your subject line is probably not the problem.
