I like that you can clone an email to re-customize it for a different target audience. For example, if you have a promotion you want to send out to the clients of several agents, you only have to design the email once and then clone it for each agent. Then, all you have to do from there is change the contact information in the email and change the "send from / reply to " email addresses.
I have not found anything I really dislike about it yet. It offers everything I've needed so far. so I'm able to accomplish all of my tasks with one program.
The price varies on how many contacts you add, but you can have the same people on multiple lists without paying more. If you aren't sure, definitely do a trial of it and even try it out on small lists so that cost is minimal while you are still trying to figure out if you want to use it.
Emails are easy to personalize, and there are plenty of fields on the contact profiles to use for this feature.
We can use this to email several different types of recipients (vendors, clients and affiliate companies.) What's great about Benchmark is that you can personalize a mass email with any information you store on each individual's profile (name, company, etc.)
