I just determined that plus addressing on email forwards broke with the transition from Google Domains to Squarespace (i.e. forwarding [email protected] to [email protected] used to also forward [email protected] to [email protected]). This means I'm now missing a bunch of emails, because as a general rule I would create a custom plus address with a relevant tag anytime I registered an email.

So now I'm wondering if anyone has thoughts on a way to get this working in Squarespace. I added a wildcard email rule as a stopgap, but even that requires 24-48 hours to take effect.

Alternatively, does anyone have any good recommendations on domain hosting providers that support email forwarding with plus addressing?

@jschuh I bailed to Cloudflare before I got dumped onto Squarespace (registrar and email forward-only) and it's been fine, and does support +addressed forwarding properly.
@sgraham Thanks. I'll take a look at it.
