Is there something I'm missing?

Export to CSV option in report exports up to 100,000 records only(by default). Email servers typically have an attachment file size limit (Gmail 25 MB, Outlook 20 MB) because of which we have to limit capabilities of Export to CSV. Estimating this size is extremely tricky depending on the number of fields, presence of long text fields, etc. We do not know if the export is going to get failed at the time of requesting export.
Does this problem only happens with Email Activity or with other reports also? Is this export required for Gainsight Admins or end users? Can you share some more use-cases around exports? We are currently evolving our data export strategy and your responses will be extremely helpful.
In today's product, as Jeevan suggested above, we recommend using Rules engine for data exports. Not only does rules engine has fewer limitations, but also it is built for such use-cases.
