Step-by-step guide
Delete the Squarespace Defaults, then add 3 DNS records: a CNAME on www, an A record and an AAAA record. Your domain stays registered at Squarespace, Heya Pro Standard connects it for $6 a month with free HTTPS, and Squarespace's old records stay cached for up to 4 hours.
Squarespace steps checked against Squarespace's own help center on November 2, 2026.
Heya shows these as soon as you connect your domain. Copy the CNAME value from Heya, since every site gets its own address.
| Type | Name | Value |
|---|---|---|
| CNAME | www |
Your own address from Heya, ending in .heyadns.com |
| A | @ |
149.248.206.36 |
| AAAA | @ |
2a09:8280:1::1ce:932e:0 |
If Squarespace calls the AAAA address invalid, enter the same address in full:
2a09:8280:0001:0000:0000:01ce:932e:0000. For a subdomain like shop.example.com, you only
add one CNAME, named shop.
Squarespace adds a preset called Squarespace Defaults to every domain it registers, and your domain can't point to another site while it's there. One click on its red trash can removes all 5 of its records.
www as
the Name, paste your address ending in .heyadns.com from Heya into Data, and click Save.
Squarespace doesn't allow @ as the name of a CNAME.
@ as
the Name, put 149.248.206.36 in IP Address and click Save. Then add one more: pick AAAA,
enter @, put 2a09:8280:1::1ce:932e:0 in IP Address and click Save. If
Squarespace calls that address invalid, enter it in full:
2a09:8280:0001:0000:0000:01ce:932e:0000.
The clicking takes a few minutes. Squarespace's records carry a 4-hour cache time (TTL), so the old Squarespace page can keep showing on some networks, and in Heya's check, for up to about 4 hours after you delete it. Squarespace's own help says domain changes can take 24 to 48 hours.
To test without an old cached copy, open your domain in a private or incognito window. Heya gets the HTTPS certificate by itself once it sees the new records, so there's nothing to set up for the padlock.
Heya tells you what it sees. These are the messages you can run into after a Squarespace change, and the fix for each.
We can't see a CNAME record on www.example.com yet.
www.example.com points at ext-sq.squarespace.com.
example.com answers with 198.49.23.144. It needs exactly A 149.248.206.36 and AAAA 2a09:8280:1::1ce:932e:0.
Squarespace shows an error when a new record clashes with one that's already there, or with a forwarding rule.
Every Squarespace step comes from Squarespace's help center: DNS records for web hosting, Pointing a Squarespace domain, Edit your domain's DNS records and Why domain updates take up to 48 hours. We read the Squarespace Defaults and their 4-hour TTL off a domain registered at Squarespace on November 1, 2026. The Heya records come from Heya's own domain setup.
Dashboards change. If a step here no longer matches what you see, email hello@heya.page and we'll fix it.
Either works, and the other one redirects to it. Type example.com and your site lives on https://example.com, with www.example.com redirecting there. Type www.example.com and it's the other way around.
Type shop.example.com when you connect the domain in Heya, and Heya shows you just one CNAME record, named shop. Add that single CNAME under Custom Records in Squarespace. You don't need to delete the Squarespace Defaults for a subdomain, because they only cover @ and www.
Domains from Google Domains moved to Squarespace, so you'll find yours at account.squarespace.com/domains and follow the same steps. If you don't see Squarespace Defaults there, delete any other A, AAAA or CNAME records on @ and www instead, since Heya's records need to be the only ones on those names.
No, as long as you leave your email records alone. Your MX records and TXT records (such as Google Workspace verification or SPF) are separate from Squarespace Defaults, so deleting the preset doesn't touch them. Deleting those records yourself is what breaks email.
No, DNSSEC can stay on. Squarespace only asks you to turn it off for ALIAS records, and Heya uses A, AAAA and CNAME records.
No. The domain stays registered at Squarespace and renews there. You're only changing its DNS records so it points at your Heya site.
Yes. Delete the 3 Heya records, then open DNS Settings for your domain, click Add preset and choose Squarespace defaults.
Heya Pro Standard is $6 a month and includes 1 custom domain per account. Pro Plus is $15 a month for up to 10. The HTTPS certificate is free and automatic on both.
