A professional email address on your own domain
anna@yourcompany.com says more than a free webmail address ever can. Here's how custom domain email works, what you need, and how to set it up in minutes, free.
Trust
People are more likely to open, answer and pay an email from a company domain than from a free address.
Brand
Every message repeats your name. Your address matches your website, your invoices and your business cards.
Control
The domain is yours. Change providers, add people or close an address without asking anyone to update their contacts.
A handful of DNS records make it work
Your domain's DNS tells the world how to handle its email. These are the records PostPike asks for. You add them once, where your domain's DNS is managed, and PostPike checks them for you.
- TXT
_postpike - Proves to PostPike that you own the domain. Only needed once.
- MX
- Tells other mail servers where to deliver mail for your domain.
- SPF
- A TXT record listing the servers that may send mail as your domain.
- DKIM
- Public keys that let receivers check each message's signature.
- DMARC
- Tells receivers what to do with mail that fails those checks, which stops spoofing.
- TXT _postpike Proves the domain is yours
- MX @ Delivers mail to PostPike
- TXT @ SPF: lets PostPike send for you
- TXT …_domainkey DKIM: signs every message
- TXT _dmarc DMARC: protects against spoofing
Which addresses should you create?
A personal address for each person, and a few shared ones as aliases, so they don't use up mailboxes.
Personal addresses
anna@: first names feel personal and are easy to sayanna.jansen@: first and last name, for larger teamsaj@: initials, short but harder to guess right
Shared addresses (aliases)
hello@orinfo@: for your website and business cardssales@andsupport@: route them to the right personinvoices@: keep bills apart, or let your AI agent file them
Tip: on Basic and Pro, for a domain whose mail is at PostPike, a catch-all address receives mail sent to any address on your domain, so typos still reach you.

Custom domain email questions
What is a custom domain email?
It's an email address that ends in a domain you own, such as anna@yourcompany.com, instead of a provider's domain such as gmail.com. You choose where the mail is hosted, and you can move it without changing the address.
What is an email domain?
The part after the @. In anna@yourcompany.com, the email domain is yourcompany.com. DNS records on that domain tell the world which server receives its mail and which servers may send it.
How much does custom domain email cost?
You need a domain, usually $10 to $15 a year for a .com. Hosting the email can be free: PostPike's Free plan covers 5 mailboxes. Paid plans, opening soon, start at €3.99 a month for the whole account, not per user.
Can I use my custom domain with Gmail?
Google only hosts custom domains in its paid Workspace plans. You can, however, read and send PostPike mail in the Gmail app on your phone over IMAP. See the guide.
Can I use a subdomain, like mail.yourcompany.com?
Yes. A subdomain works the same way as a domain, with its own records. Most people prefer the shorter address on the main domain, though.
Does custom domain email affect my website?
No. Email has its own DNS records, so your website, wherever it's hosted, keeps working exactly as before.
