One of my users wants to send a one off email to over 70,000 external recipients. What is the best way of doing this through Notes? My SMTP server is fine for normal day to day business, but I’m worried it won’t be able to handle such a large amount of sudden traffic. I also don’t want to tell my customer to either create a group of all these 70,000 people, or to send several lots of emails to different people to get round the size restriction in the To field.
use a database that is designed to send out large amounts of e-mails, like an e-mail blaster.I have one that would handle what you are asking for but there is a cost to it
You might also want to consider if this action could get your domain listed in various blacklists, etc. Perhaps it would be better to send the email from a broadcast mail service.
