DiscoveredGet the total number of Marketing Campaigns contacts on your account. Returns { contact_count, billable_count }. SendGrid: GET /v3/marketing/contacts/count.
DiscoveredGet global email statistics over a date range (delivered, opens, clicks, bounces, spam reports, etc.). Returns an array of { date, stats: [{ metrics: {...} }] }. SendGrid: GET /v3/stats.
DiscoveredGet a single transactional email template by id, including its versions (subject + content). SendGrid: GET /v3/templates/{template_id}.
DiscoveredList bounced email addresses (the bounce suppression list). Returns an array of { created, email, reason, status }. SendGrid: GET /v3/suppression/bounces.
DiscoveredList globally-unsubscribed email addresses (the global suppression list). Returns an array of { created, email }. SendGrid: GET /v3/suppression/unsubscribes.

DiscoveredLook up marketing contacts by exact email address (a read-only lookup — mutates nothing). Returns { result: { "<email>": { contact: {...} } } }. SendGrid: POST /v3/marketing/contacts/search/emails.
DiscoveredSENDS A REAL EMAIL immediately via SendGrid. Provide `from_email` and one or more `to` recipients, plus EITHER a subject + content OR a `template_id` (dynamic template ids start with "d-", pass values via dynamic_template_data).
