I can't speak to Elastic Email's internal platform as I haven't used it much (composing emails inside their dashboard, creating campaigns, etc.). So I'm not sure how well the platform works for scenarios where that type of interface/feature set would be required, but I do know that if you need to hook external services to their SMTP or API, you'll have a great experience. Everything is super straightforward, the system is reliable, and the price is hard to beat.
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.
I have not had any issues with Elastic Email that have required reaching out to support, so I can't speak to the quality of their customer support. The help documents were well written and presented, though, and I would imagine that anyone with issues would receive satisfactory assistance in a timely manner.
Email elastic is a cost-effective, fast, and reliable platform for sending bulk emails and promoting campaigns, it provides good features even for the new user, while Blaze Verify pricing is a bit high, and a new user would not be able to access all the features. Hence clearly, Elastic email leads the position when compared to Blaze Verify.
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.
