Why an email was not sent

Before an email is queued, Azimea checks whether the person’s consent status allows this kind of message. When it does not, the email is stopped: its status becomes Suppressed, the reason is written on it, and a flow’s history shows “Email not sent” with the same reason.

Status or reason	What it means	What you do
sending.gate_bounced	The person's address does not work any more.	Nothing: the address is no longer used.
sending.gate_complained	The person marked one of your emails as spam.	Nothing: they are never written to again.
sending.gate_no_basis	The person has not subscribed and is not an existing customer, so marketing may not reach them.	Expected for people who only typed their address at checkout. To reach them, ask for consent; or make a message about their own order a service email.
sending.gate_not_declared	You have not yet declared how your shop collects consent, so no marketing goes out, even to subscribers.	Settings › Consent: choose your method and declare it.
sending.gate_soft_opt_in_off	The person is an existing customer, but your shop uses a consent checkbox, not a notice at checkout, so buying alone does not allow marketing.	Expected with a checkbox: only those who ticked it receive marketing. Switch to notice at checkout only if your checkout really shows that notice.
sending.gate_topic_opted_out	The person turned off the topic this email belongs to; they still receive your other topics.	Nothing: respect their choice.
sending.gate_unsubscribed	The person unsubscribed from your marketing emails.	Nothing: they said no. Service emails still reach them.

Service emails (about the person’s own order or account, with no offer) only need a working address, so only gate_bounced and gate_complained can stop them.
