Add advancedsending cname

[adrianaleonte]

Description

Adds advancedsending.com.cname.json — a generic, signed, variable-driven CNAME
template for Advanced Sending Connect, a Domain Connect Service Provider operated by
Ideal Web Construct SRL (advancedsending.com). It points a customer's subdomain at
our service — for custom domains, branded links, open/click tracking, SMS short-links and
CDNs.

It is a shared template: many SaaS customers reuse this single signed template, passing
their brand via the providerName parameter (sharedProviderName) and their destination
host via the %target% variable. The subdomain label is supplied via the standard host
parameter (hostRequired: true), not a variable.

Type of change

• New template
• Bug fix (non-breaking change which fixes an issue in the template)
• New feature (non-breaking change which adds functionality to the template)
• Breaking change (fix or feature that would cause existing template behavior to be not backward compatible)

How Has This Been Tested?

• Template functionality checked using Online Editor
• Template file name follows the pattern <providerId>.<serviceId>.json (advancedsending.com.cname.json)
• resource URL provided with logoUrl is actually served by a webserver (https://connect.advancedsending.com/static/logo.svg → HTTP 200, image/svg+xml)

Checklist of common problems

• syncPubKeyDomain is set — connect.advancedsending.com; the public key is published as TXT at _dcpubkeyv1.connect.advancedsending.com
• warnPhishing is not set alongside syncPubKeyDomain — the field is present but explicitly false (the template is signed); it is not the prohibited warnPhishing: true fallback. Happy to drop the field entirely if you'd prefer it absent.
• syncRedirectDomain is set — advancedsending.com
• no TXT record contains SPF content — N/A (no TXT records in this template)
• txtConflictMatchingMode is set on unique TXT records — N/A (no TXT records)
• no variable is used as a bare full record value — N/A; the only variable is the CNAME pointsTo (%target%), a hostname, which is necessary for a shared custom-domain template
• no bare variable is used as the full host label — the record host is @ (fixed)
• no variable is used in the host field to create a subdomain — the subdomain is supplied via the host parameter, with hostRequired: true
• %host% does not appear explicitly in any host attribute
• essential is set to OnApply on records the end user may need to modify or remove — set on the CNAME

Online Editor test results

Editor test link(s):
Test advancedsending.com/cname example.com/link

With hostRequired: true, the apex test is exempt (per the template note); the test above uses a subdomain — host=link, target=sms.advancedsending.com — producing CNAME link.example.com → sms.advancedsending.com.
