How can Enterprises send bulk marketing emails (80,000+ emails)?
Use *anything* other than O365, as you risk getting your entire tenant blocked. Whether it's a 3rd party or home-grown solution, depends on multiple factors, so it's up to you to decide. But don't even try to use O365 as a bulk-messaging tool, unless you want to spend hours on the phone trying to restore proper mail flow.
VasilMichev I plan to use O365 (word+excel+outlook) to send bulk mail (5000/day). Will this cause problem?
VasilMichev, further update -
Agreement to use 3rd party to send out emails (mostly nailing down to SENDGRID)
As no Exchange On-premise server, because migrated all mailboxes to Office365 and Exchange servers are decommissioned.
In such case, looking at SMTP relay that will be used to forward the mail to SENDGRID.
questions:
a) Onpremise Application that will be sending bulk emails, not sure if recommended to directly configure the SENDGRID details on the appplication.
Looking at security standpoint, wont that affect or expose the application server (port 25 only allowed, but worried if system can be compromised)?
b) If SMTP gateway used, such as LINUX system with SMTP relay do you see any issue or point of advice.
Thanks in advance.
Many 3rd party solutions are out there, i would highly recommend using those. You not only get delivery of your messages but you get full tracking and campaign capabilities so you can get click tracking, open rates (although these are mostly worthless) spam anaylitics all kinds of things you get when using a 3rd party product vs. using an exchange server where you really don't get any analytics and your doing blind marketing.
