The sending steps depend on each other and must be done in this order:
- Billing details: company name, country and tax number on Settings › Invoices. Without them no plan can be bought.
- Plan: the trial does not include sending; subscribe on Settings › Plan. Without a plan no domain can be connected.
- Sending domain: add your domain on Sending › Domains and wait until its DNS records are verified.
- Sender profile: create a profile with the verified domain and your company address for the footer.
- Campaign: pick a list whose emails you approved in AI personalization and launch the campaign.
The Setup checklist and the Not ready to send card on the Dashboard show which step is missing; both link to the next step.
If all of this is done and a campaign still isn't sending, see "My campaign started but emails aren't going out".
