Finding out if a series of job emails from the same person are a scam or a way of tracking/phishing?

Question

I'm Indian, and have received a third job email from a Canadian "Co-founder and COO". I'm not even actively job searching.

1. He hasn't mentioned how he got my mail id or why I'm the right fit for the job.
2. Google's "secret sauce" shows the yellow icon that probably indicates the email is not spam.
3. The emails have images which GMail has hidden for safety reasons, and I was careful not to click on the "Display images below" link.
4. His email signature contains a "We're hiring" link that leads to: https://hiscompany-dot-yamm-track.appspot.com/Redirect?ukey=1wQLKWIOnoiYyfDopetkntTdf7QKeYeABTwjUQf1vzCU-551884202&key=YAMMID-12656006&link=https%3A%2F%2Fhiscompany.io%2Fjoin-hiscompany%2F. I didn't click it.

I ignored the first two emails because they almost exclusively speak of immigration, permanent residency and Canadian citizenship.

Questions:

1. Is there any danger in just replying to find out if the offer is genuine? It doesn't follow the typical scam email pattern, but could just be an improvisation. This degree of persistence could also point to jobs that exploit people in exchange for Canadian citizenship. Perhaps even another University of Farmington.
2. In case it's a scam, I believe the typical modus operandi would be to send a malicious PDF. I wonder if simply replying to him or clicking any of the links in his email would give him enough of info about my computer or phone to compromise it?

For the reference of anyone who receives similar emails:

Hi MyName,

I just wanted to follow up on the email I sent a few days ago about Machine Learning opportunities we have at HisCompany. I'm not sure if you've ever considered relocation to Canada, but it is easier than most people are aware. Our immigration team can usually get an engineer (and their family) immigration visas in as little as four weeks.

I'd be really excited to tell you more and answer any questions you might have, so if you're interested please let me know with a quick reply.

Thanks again MyName,

Answer 1

This looks like a scam to me.

The Link to "their recruiting-site" is really a red flag for me. Not explaining the reason, why they reach out exactly to you and how they got your contact is also not professional at all.

One possible scam scheme could work like this:

1. Send E-Mails.
2. Send Follow-Up-Emails until you believe it's legit.
3. Make some promises about a great job and a permanent residency in Canada.
4. Request some money for the paperwork (visa, work permit, etc.)
5. Find more reasons, why they need some more money or information
6. repeat #4 and #5 until you give up

However there might be numerous other schemes, that could allow him to make money, gain information or your trust.

Edit: If you were to click the links or load the images in the mail, he'd probably able to identify your OS, Browser, Browser-Plugins, rough location (based on IP), validate your e-mail address. This can, in rare cases, be sufficient to successfully compromise your system, depending on patches, etc.
