Validated live with Mailjet: targo.ca is verified at the DOMAIN level
(SPF + DKIM + DMARC published in Cloudflare), so any *@targo.ca sender
works without per-mailbox approval. Tested 1 send from
support@targo.ca → accepted, delivered.
Why support@ rather than noreply@ for campaigns:
- Campaigns INVITE a reply (questions about the gift, "I didn't get
mine", "the link doesn't work", etc.)
- noreply@ is for transactional system mail where there's nothing
useful for a human to reply to
- Different intent → different sender
The hub's transactional emails (invoices, magic links) continue to
use noreply@targo.ca; campaigns specifically use support@targo.ca.
README updated accordingly with the rationale.
Note for future: if we ever want a @gigafibre.ca sender, that's
~30 min of Mailjet setup (add domain, publish SPF/DKIM CNAMEs in
Cloudflare). Not done today because all customer-facing email
flows through targo.ca and support@ is the right mailbox for this
campaign intent.
