iMailXS+ – Unlimited version

An unmatched solution offering virtually no limit to your Business Emails space & its features. iMailXS+ Unlimited version is the best solution if you are looking for freedom to every feature, freedom to space, freedom to usage.

iMailXS+ Unlimited comes packaged in per Email package. Every email has virtually Unlimited space with a FUP (Fair Usage Policy) limitation of 50GB per email ID. However, you can utilise the space of other accounts who do not use the entire 50GB space, making iMailXS+ the only Business Email solution with such a Unique feature.


Unlimited version of iMailXS+ consists of all the Features provided by the Enterprise version plus some unique additional features listed :

iMailXS+ is the only Business Email solution in the world providing virtually Unlimited Email Space. However, it comes with a FUP (Fair usage policy) : Each account is allowed 50GB per ID per domain, but you are free to use spare Email Space of one account into another. For example, you enroll for a pack of 100 Email Accounts, entitling you to get 50GB x 100, i.e. 5000GB space allocation per your business-domain, due to FUP applicable. There may be say 50 accounts using only say 1GB space. However, FUP entitles you to use the balance 49GB x 50, i.e. 2450GB in even just a single account. Sounds crazy ?

All Account Email Archival is an extremely unique feature of iMailXS+, but with Enterprise version it also comes with Offline Monthly based CD with Email browsing software. A copy of All Email (both Incoming & Outgoing) can be browsed Offline (with limited Internet Connection for Authentication purpose only), hence making backup copy of each & every email received & sent by your Business Email accounts for any period.
