Aside of the easymerge service, there a few launchpoint partners that can help:
And BtW, other vendors (e.g. salesforce) have the same policy. SFDC CRM provide a duplicate prevention (with which you can prevent the creation of duplicates) but no mass merging feature.
At Grazitti Interactive we have helped many Marketo customers with our custom de-dupe solutions for real time lead merge and clean database in Marketo.

I think you are better off just thinking about it as Marketo does not have an out of the box mass merge solution and you need a third party tool.
The EasyMerge service was designed for one specific scenario - if you are using Marketo standalone at first and have a large number of people in your database, then decide down the track to sync it to a CRM (it was designed specifically for Salesforce but it can be used for Dynamics in certain circumstances) the rules governing the Marketo-Salesforce sync mean if you have the same leads in your CRM you'd get duplicate leads in Marketo on the initial sync.
EasyMerge was designed as a one-off service to help use a rules-based solution to merge these leads. It wasn't (and isn't) designed as a solution for long term or everyday use. Considering how much time it takes to develop these rules and to test the merge to ensure no mistakes are made (trust me, I've done it), EasyMerge as a service is pretty good value, it just isn't a solution for anything other than the situation I've described above.
Veronica hit the nail on the head... using EasyMerge for anything other than one-off database merging doesn't make any sense.
In my time as a Marketo enterprise consultant, I had many clients have great success with some of the launchpoint partners that provide the on-demand services that you seem to be looking for. Personally, I have had great experiences with RingLead.
I did have a client that used Marketo's EasyMerge on a bi-annual basis. For their purposes, they could justify the annual cost, and it performed the function they were looking for. Their goal was to keep their duplicates at less than 2% of their database, but were on a very aggressive acquisition calendar, so about every 3 months they seemed to have another giant batch of names come into their system, so the regular easymerges made it possible.
