InboxKit Domain Coupon Code 10% Off Domains
Use GET50 for 10% off domains you buy through InboxKit, then connect them to Google, Outlook or Azure mailboxes with DNS configured automatically.
Why buy your domains through InboxKit?
Cold-email teams use separate domains so outreach never affects their main company domain. When you buy domains through InboxKit, they're already in the same account as your mailboxes. InboxKit sets up SPF, DKIM, DMARC and MX records for you, and each domain gets its own admin panel, so a problem on one domain doesn't spread to the others.
How much GET50 saves on domains
Domain prices on InboxKit depend on the extension (.com, .co, .io and so on), so we don't list one fixed price. Whatever the price at checkout, GET50 takes 10% off. If you buy 20 domains for a new campaign, that works out to about two domains free. You can enter your own domain price in our savings calculator.
How many domains do you need?
A common setup is 2–3 mailboxes per domain on Google or Outlook, so the number of domains follows from the number of mailboxes you need. Azure works differently: one domain can hold up to 100 mailboxes, so you need far fewer domains. See the Azure coupon for that option, or work out the exact number in how many mailboxes you need for cold email.
Your own domains or new ones?
You can connect domains you already own to InboxKit mailboxes. The 10% discount only applies to domains you buy through InboxKit. Buying through InboxKit has practical benefits: the domains are ready to connect straight away, DNS is configured for you, and your domains and mailboxes are managed and renewed in one place. If you're starting a new outreach setup, buying fresh domains keeps your main company domain completely separate from cold-email sending.
How to apply the domain coupon
- Open InboxKit through our link and sign up.
- Search for and add the domains you want.
- Enter GET50 at checkout.
- Confirm the 10% discount, then complete the purchase.
Domain naming tips for cold email
- Use close variations of your brand (try-brand.com, getbrand.com, brandhq.com).
- Prefer well-known extensions like .com and .co over unusual ones.
- Set up forwarding from each domain to your main website so recipients who visit can find you.
Then add mailboxes: 15% off Google or 20% off Outlook with the same code.
