TinyCampaigns is the sending machinery that sits behind the templates you design in TinyEmails: audience resolution, a durable per-recipient queue, throttling, your own sending domain, suppression, bounce handling and reporting.
Verify a domain once with three DKIM records and every address on it becomes a valid sender. Name a consent column on your table and the gate is fail-closed — a row has to match an allowed value to be queued at all.
Hard bounces, complaints and unsubscribes suppress themselves, and the suppression list is checked twice: once when the audience is built and again immediately before each message goes out. Unsubscribe is RFC 8058 one-click, so Gmail and Outlook show the native button.
If bounces pass 5% or complaints pass 0.1% after fifty sends, the campaign pauses itself rather than burning your domain reputation.
