"Easy Setup for Microsoft 365"
4/5
What do you like best about N-able Mail Assure?

Setting up the Mail Assure is quick and easy especially for Microsoft 365. Even someone without any experience in integration can simply look at the guide and be able to do it. I like how fast and easy it is to integrate the domains and mailboxes for Microsoft 365 without complexity. And this is not just for Microsoft 365 but for Google workspace as well. It doesn't have the same level of integration as M365 but setting it up is also quick and easy.

Another thing is that the dashboard, with the bar and pie charts is easy to understand so you can quickly analyze the data. Review collected by and hosted on G2.com.

What do you dislike about N-able Mail Assure?

I am just not comfortable with the way Mail Assure uses MX records to catch emails. As an attacker there are ways to avoid this like direct to IP attacks so I still need to think of a strategy on how to remediate holes like this. Review collected by and hosted on G2.com.

"Spam Filtering with 365 Syncing"
2.5/5
What do you like best about N-able Mail Assure?

Mail Assure provides spam filtering and integrations if you already use the N-Able platform. They offer 365 syncing so you don't have to remember to add new users to the spam filter. It's easy to go through logs and find mail being blocked and you can do advanced searches once you have a message ID in order to see the reason why specifically it was blocked. There is a self-service portal for end users but it's not intuitive for them usually. Review collected by and hosted on G2.com.

What do you dislike about N-able Mail Assure?

It really comes down to service support and the billing side of N-Able. Their support is slow to respond if you can get them on the phone that's the best way. We've found they create hidden charges making it difficult to pass these things on to your client. Cancelling services has also been difficult with things coming back into the Review collected by and hosted on G2.com.

"Best Email Security Platform for users with high emails!"
4.5/5
What do you like best about N-able Mail Assure?

N-able Mail Assure is one of the best email security platforms that anyone can find. This platform provides the best support and features. I have used it for almost a year but I never encountered a problem while using it. The main feature of this software is actually the anti-phishing protection that it gives. Review collected by and hosted on G2.com.

What do you dislike about N-able Mail Assure?

I didn't like the integration of this software. It doesn't comply with many email services, so that's something this software can improve, and aside from that, everything is good. Review collected by and hosted on G2.com.

"Avoid this service at all costs"
0/5
What do you like best about N-able Mail Assure?

The branding is certainly the only positive option of this service. For those looking a white SAAS service, they do have it. Review collected by and hosted on G2.com.

What do you dislike about N-able Mail Assure?

- Poor technical support - Poor interface management - Not convenient to retrieve email archives - And the WORST: they do have huge problems respecting the invoicing process resulting in multiple occurrences of overbilling and our bank account has been withdrawn on two occurrences for amounts way above the amount due. Which is totally unacceptable. - Impossible also to reconcile the amounts withdrawn from our bank account with their invoices. - Getting our money back has been a colossal amount of emails and time. You want to lose your time and reputation? Go with these guys. No serious expert would deal with such crap. Review collected by and hosted on G2.com.
