Hi! I have a question about sending emails via SMTP.
Sometimes I need to send individual emails to clients with an attached file (like a contract), but not from our CRM. I’m considering uploading a full list of emails (10–20k contacts) into an email client and sending them via SMTP.
Will this be treated as spam by services like Gmail if sent all at once? Should I add delays between emails?
Also, how fast are emails sent through SendPulse SMTP? Is there a risk of them going to spam because of sending speed?
Additionally, is it possible to send a unique attachment (like a personalized contract) to each contact using SendPulse?
