A part of code on my email cause to be blocked by recipients

They informed me from my hosting provider, that a block of code on my email (sending through MailWizz) is causing my emails to be marked as spam. They told me that my emails have been reported by multiple providers (such as Yahoo or Comcast) as containing spam. This caused my email account blockage. Now they unblock it, though they didn't reply to me which part is causing this even when I asked them.

On my emails I have just plain text (2 words of them with links to my site), an image 143kb (600x735px) with a link to my site, my contact details and an unsubscribe link. I am sending them to valid recipients. Do you have any ideas of which part of the email might be considered as spam?

If http://www.mail-tester.com does not show you what and why, then perhaps https://litmus.com/spam-filter-tests or https://glockapps.com/spam-testing/ might help.
Please let us know if you find a better testing tool and what the reasons were!

on mail-tester I get 2/10

the negative score caused mainly by these:
1. [SPF] mydomainname.net does not allow your server XX.XX.XX.XX to use myemail@mydomainname.net
2. [Sender ID] mydomainname.net does not allow your server XX.XX.XX.XX to use myemail@mydomainname.net
3. my email appears in 3 blacklists (spamcannibal, lashback and sorbs-spam)

and secondly by these:
4. You do not have a DMARC record
5. Your reverse DNS does not match with your sending domain.

I think I understand only number 5. as it appears to sending from one email of mine and I will get replies to another email of mine. I will fix this but please let me know if I get it right.

Any others ideas what I can do?

Thanks!

#1 - Add proper DNS SPF records, generate them using https://www.spfwizard.net and add them as DNS TXT records.
#2 - It;s still related to SPF, make sure the server from where you send the emails is allowed in the SPF records.
#3 - It's not the email but the IP address. Each blacklist has it's own delisting process, so you should look into it and try to get delisted.
#4 - DMARC is also a DNS TXT record. Use a generator such as https://www.unlocktheinbox.com/dmarcwizard/

Hope it helps.
