I've mostly used YAMM for quick updates to people I've previously corresponded with. Though I have the option to insert their names into the emails all fancy-like, I usually err on the side of caution and write universal email drafts for everyone I'm sending to. Great app!
I set it up within minutes. The google sheets integration is smooth. Sent out campaign to 300+ in one day with personalization and scheduling. The feature set is pretty expansive. Looking forward to use the Saleforce integration. If it works well, that would be epic! Very straightforward to use and measure success
Meanwhile I think an onboarding guide will really help after setting up the account. Somehow I missed it and had to spend a bit of time to understand how to setup my first campaign.
Straight forward mail merge with google sheets and gmail.
I've been using YAMM for over a year now. I've used it for investor / stakeholder updates, team updates, etc. In terms of efficiency, I save a boatload of time and can keep track of who is getting my messages.
It's the best of it's class.
I've been using this for a little more than a year. Love the tracking features, love the separate folders in my inbox, plus, it's reasonably priced.
The company I work for uses HubSpot. I HATE HubSpot. Everything about it. It's super poorly engineered. With any email messaging, I use YAMM. Have been using this for three years on several different projects, and have never been let down once. Also, I've had feedback, and it's always been listened to (and implemented). Really can't say enough good things about this product, and the leadership behind it.
Been a user for over two years. Great service and make testing campaigns a breeze.
