Hi Acumbamail Support,

I am using my account to send automated 6-digit signup verification codes (OTPs) for my new app.

My domain has fully verified DKIM, SPF, and DMARC settings. However, my API calls to the sendOne endpoint are returning a 401 error: 'SMTP is not active for your customer'.

Could you please manually activate the transactional SMTP/email flag for my account so my application can begin sending? Thank you!
