Top Seven Cloud-based Tools I Use Every Week
Social Mention
I use Google Alerts to keep track of our brand mentions, but I use Social Mention a couple of times a week. It picks up stuff that Google doesn't seem to know about.
HubSpot's Marketing Grader
I have used the Marketing Grader since it used to be a bunch of separate Graders, and while it isn't always accurate, it helps to mark your progress as well as indicate what you might be doing wrong.
Constant Contact
I have used Constant Contact for email marketing for several years, and while I've complained in the past about it being difficult to use, they have improved a lot in the past year or so. I wish it was faster, but I build newsletters and email announcements (or holiday cards) on it several times a month and am pretty pleased with the interface.
Remember the Milk
When I first heard of the site I was skeptical: they just send you reminders? That's it? But I've used it to keep track of personal tasks (pay bills, call the plumber) and it works very well. It's very easy to use, you can share tasks with someone else (like your spouse or roommate), and it sends you an email reminder. Even though I use Google Calendars and phone reminders, I still prefer Remember the Milk for this purpose.
Google Docs
Funnily enough, my husband and I communicate online quite a bit, and we use Google Docs to keep track of things such as our finances (tracking expenses, keeping a running list of movies we want to watch, sharing flight or train tickets). So when we transitioned from Outlook to Google last year, I was glad to start using Google Docs in office too.
I am going to continue to use Word because of its Track Changes feature (Google's Revision History just isn't as nifty), but Google Docs is easier to share lists that others can add to.
