Keplars vs. SMTP Email Relay Solutions

SMTP Email Relay Solutions is a great service if you are in a field where sending out bulk information, such as monthly statements to clients, invoices, or any back-to-back emails that would normally get flagged for "spam" is required.

• It allows us to send email through the secure email gateway.
• We are able to track and scan all email communications
• It provides a way for legacy and current applications to send out notification and mass email communications.

• As with any technology on a server, we sometimes see issues with downtime related to network changes or firewall updates.
• It can be a challenge to work with some of our older applications when the TLS feature is used.
• I wish there was a more direct way to reliably use SMTP for mass email sends without the fear of being blacklisted.

I have yet to encounter any hiccups with their services. I send a large volume of emails monthly and have yet to experience any delay in my work.

Office 365 does use secure non-standard ports for SMTP connectivity causing a problem with older programs. SMTP Email Delivery from Exchange solves this problem by giving the network admin full control over ports and specific program connections. While we do use both Office 365 and the SMTP Email Delivery we find that a mix is needed in order to meet all expectations for our end users. The majority of our SMTP communications, for users, go through Office 365 while the majority of our applications and servers do go through the SMTP Email Delivery service.

• It's the easiest way to send mail out. No worries about complex configurations.
• It can be finicky when used in a hybrid Office 365 environment to get the proper pathways secured and working.
• I wish there were a better way to send out mass emails, on-site, without our domain or server IP being blacklisted.
