Hey interviewgemini.com, just wanted to follow up on my last email.
We just launched Call the Monster, an parenting app that lets you summon friendly ‘monsters’ kids actually listen to.
We’re also running a giveaway for everyone who downloads the app. Since it’s brand new, there aren’t many users yet, which means you’ve got a much better chance of winning some great prizes.
You can check it out here: https://bit.ly/callamonsterapp

Hi, are you owner of interviewgemini.com? What if I told you I could help you find extra time in your schedule, reconnect with leads you didn’t even realize you missed, and bring in more “I want to work with you” conversations, without increasing your ad spend or hiring a full-time employee?
All with a flexible, budget-friendly service that could easily pay for itself. Sounds good?
Would it be nice to jump on a quick 10-minute call so I can show you exactly how we make this work?
Best,
Hapei
Marketing Director
