Step-by-step for your provider
Pick where your domain is managed to see where its DNS records live and what to type in each box. The records themselves come from Centrx: here’s how to get them.
GoDaddy
- Sign in to GoDaddy, open your domain list and select your domain.
- Open the DNS tab and select Add New Record.
- Choose the Type Centrx shows. In Name, enter the host from Centrx, like
abc123._domainkeyorbounce. Paste the Value and leave TTL as it is. - Select Save, then add the next record. Add More Records lets you add several before saving.
GoDaddy adds your domain to the end of the name, so enter abc123._domainkey, not abc123._domainkey.yourbusiness.com. On GoDaddy's older screen, it's Edit DNS in the menu next to your domain, then Add. If GoDaddy says your domain uses other nameservers, add the records with that company instead.
Namecheap
- Sign in, open Domain List and select Manage next to your domain.
- Open the Advanced DNS tab. Under Host Records, select Add New Record.
- Choose CNAME Record, TXT Record or MX Record, enter the Host and paste the Value. Leave TTL on Automatic.
- Select Save all changes, then add the next record.
Namecheap adds your domain to the host for you: enter abc123._domainkey or bounce, exactly as Centrx shows it. If Host Records is missing or locked, your domain uses another company's nameservers (often your web host's), so add the records there.
Squarespace
- Open your Domains dashboard and select your domain.
- Select DNS, then DNS Settings, and scroll to Custom records.
- Select Add record. Squarespace may ask for your password or two-step code first.
- Choose the Type, enter the Name (like
bounce) and paste the value into Data. For the MX record, enter10as the priority. Select Save, then add the next record.
Custom records only work when your domain uses Squarespace's nameservers. If the domain is only connected to Squarespace and was bought somewhere else, add the records there. If you see Custom record not saved, a record with the same name probably exists already. Check the name and edit that record instead.
Cloudflare
- Sign in and select your domain.
- Go to DNS, then Records, and select Add record.
- Choose the Type, enter the Name and paste the Target (CNAME), Content (TXT) or Mail server (MX, with priority 10).
- For CNAME records, turn Proxy status off so it shows DNS only. Then select Save.
The DKIM records must be DNS only (grey cloud). If they're proxied (orange cloud), inboxes can't read them and verification fails. TXT records are always DNS only. Cloudflare changes usually show up within a few minutes.
Porkbun
- Sign in to Domain Management.
- Next to your domain, select Details, then the edit icon next to DNS Records.
- In the form at the top, choose the Type, enter the Host and paste the value into Answer. For the MX record, the priority is 10.
- Select Add, then add the next record.
Porkbun shows your domain next to the Host box, so type only the part before it, like abc123._domainkey, bounce or _dmarc.
Wix
- Go to Domains in your Wix account.
- Select the Domain Actions menu next to your domain, then Manage DNS Records.
- In the CNAME (Aliases), TXT or MX section, select + Add Record.
- Enter the Host Name and Value, then select Save. For the MX record, the priority is 10.
You can only add records in Wix if your domain is connected to Wix by name servers. If it's connected by pointing, add the records where you bought the domain.
Other providers
Every DNS screen works the same way, but the boxes have different names. Look for a page called DNS, DNS records, DNS zone or Advanced DNS, add a record, and match the boxes like this:
| In Centrx | Your provider may call it |
|---|---|
| Type | Type, Record type |
| Host | Name, Host, Host name, Record name |
| Value | Value, Points to, Target, Content, Data, Answer |
@ means your main domain. Some providers want you to type @, and others want the box left empty. If the provider shows your domain next to the box, type only the part before it.
Not sure who manages your DNS? Look up your domain's nameservers with any free DNS lookup site. Nameservers ending in domaincontrol.com are GoDaddy, registrar-servers.com is Namecheap, ns.cloudflare.com is Cloudflare, porkbun.com is Porkbun and wixdns.net is Wix. Add the records at that company.
Who can use this
Sending from your own domain is Business Email, an add-on for any plan, Free included, at $9/month per domain. Billing starts when the domain is verified, not when you add it. On Free, you add a card first. Business and Enterprise will be able to connect with one click (coming soon). On every plan, you can follow the steps below. Without it, email comes from [email protected] with your business name as the sender, and it works without any setup.
What to have ready
- A domain you own, like
yourbusiness.com. - A sign-in for the place that manages its DNS. That's usually where you bought the domain, such as GoDaddy, Namecheap, Squarespace or Cloudflare.
If someone else set up your website, ask them to add the records for you. It takes them a few minutes.
Connect your domain
- In Centrx, open Settings → Email.
- Enter your domain and the address to send from, for example
[email protected]. - Centrx shows six DNS records. Copy each one into your domain's DNS settings exactly as shown. See the steps for your provider.
- Back in Centrx, select Verify.
The records look like this. Centrx shows the exact values for your domain, with a copy button next to each one.
| Type | Host | Value |
|---|---|---|
| CNAME | abc123._domainkey | abc123.dkim.amazonses.com |
| CNAME | def456._domainkey | def456.dkim.amazonses.com |
| CNAME | ghi789._domainkey | ghi789.dkim.amazonses.com |
| MX | bounce | 10 feedback-smtp.us-east-1.amazonses.com |
| TXT | bounce | v=spf1 include:amazonses.com ~all |
| TXT | _dmarc | v=DMARC1; p=none; |
DNS changes often show up within minutes, but can take up to 48 hours. If verification doesn't pass straight away, try again later. Email keeps going out from [email protected] until the domain is verified.
What the records do
| Record | Type | What it does |
|---|---|---|
| SPF | MX and TXT on bounce | Lists who is allowed to send email for your domain, and where bounces go. |
| DKIM | CNAME | Signs each email so inboxes can tell it really came from you. |
| DMARC | TXT | Tells inboxes what to do with email that fails those checks. |
Together they keep your email out of spam folders and stop others from sending email that pretends to be you.
Good to know
- Already have an SPF record? Leave it. Centrx's SPF record goes on
bounce, so it doesn't touch the one on your main domain. - Already have a DMARC record? Keep yours and skip ours. One is enough.
- Your mailbox keeps working. These records don't change where your email arrives.
- Adding all six at once is fine. Centrx checks them together when you select Verify.
If verification fails
- Wait an hour and try again. Most failures are DNS that hasn't updated yet.
- Check for typos and extra spaces, and make sure the value wasn't put in quotes twice.
- Check the host on the MX and SPF records is
bounce, not@. - Make sure you edited the DNS where the domain's records actually live. If you moved DNS to another provider, edit it there.
