So I've been doing freelance design for this company and I work through email and my website with this one client. I have a Chrome extension that let's me track activity on an email after it has been sent. This client last read one of my emails about 10 days ago, then I send another 2 regarding changes he requested on the design. And today I sent a follow up mail and none of these have even been read. This client is really nice, I've worked with him on two other projects (aside from the current one) and also talked about the next one. Should I be worried that he hasn't replied or even read my emails? On one of the previous projects he vanished for like a week or something, and came back to tell me he was really busy and couldn't make time to answer me (which I completely understand). I'm just worried since I didn't ask for an advance for the current project and we're half-way through. I probably shouldn't worry at all and should just wait for his answer but I thought that reading some of your stories/advice would make me worry a little less.
It honestly sounds like he is having issues, in his personal life and is having trouble keeping up. I would recommend setting bi-weekly meeting via video conference. It let's you stay in touch and is non-invasive.
