What do you use to send so you can tell if the emails were opened?

I was using VPS with mailwizz. Deliverability issues started last year and it continued dropping. I used to use one domain to send maximum 10k.

I tried bulk gmail account set up with mergo and warmed up slowly but accounts which I had bought were getting cancelled by gmail and then I used workspace which also got blocked.

Yeah this is the wall a lot of ppl hit now Cold email isn’t dead but it’s under way more pressure ESPs and filters got smarter and B2C cold is extra brutal. Main diff between spam and cold is consent + intent Cold email follows laws like CAN-SPAM or GDPR and is sent 1 to 1 with value Spam is bulk blasts with no opt-in no personalization no care

If every email lands in spam it's usually from:
– bad domain rep
– poor warmup
– generic copy
– dirty list
– no SPF DKIM DMARC
– links flagged or trigger words

For cold email now:
– use aged domains
– warm up slowly with inbox tools like Instantly or Mailreach
– go plain text
– use custom tracking domains
– segment lists tight
– rotate sending IPs and identities if needed

B2C is tough yes but not impossible if you go soft with intro value no links and build convo over time Otherwise go SMS or push or build your own owned list via SEO or ads for more control. Mass blasting = dead. Smart outreach = still alive.

1. Domain Warmup 2.0
   
   • Not just volume ramping, but reciprocal engagement:
     
     • Seed accounts that reply to your warmup emails
     • Use IMAP sync tools to simulate real user activity
     • 30-50% of warmup traffic should be inbound to your domain
2. Content Obfuscation
   
   • Loan keywords trigger filters instantly. Try:
     
     • Replacing "loan" with "l0@n" in HTML (visible as normal text)
     • SVG-based text for critical CTAs
     • Multi-part MIME with plaintext mirroring HTML content
3. IP Rotation Math
   
   • The 10 IPs/10 domains setup needs adjustment:
     
     • 1 IP should handle multiple domains (3-5)
     • Rotate based on receiver domainsnot just volume
     • Gmail pattern: 60% of traffic to Gmail, 40% to others
4. Tracking That Doesn't Burn You
   
   • Standard pixels get flagged. Use:
     
     • DNS-prefetch tracking
     • Load-balanced tracking domains that also serve real content
     • Engagement detection via read-receipt loopholes

Bulk email headaches almost always come down to one of three things: authentication, reputation, or list quality. In that order.

First check authentication. Run one of your sending domains through mail-tester.com and see what score you get. If you're below 9/10, your SPF, DKIM, or DMARC has an issue. Fix that before touching anything else. Most people skip this step and spend weeks "optimizing content" when the real problem is a missing DNS record.

Second is reputation. New IPs and domains have zero trust with Gmail and Outlook. You can't just spin up a fresh server and blast 10K emails. Warmup for 3-4 weeks minimum, starting at 5-10 emails per day and gradually ramping up. Any shortcut here gets you blacklisted within days.

Third is list quality. If your bounce rate goes above 2% you're actively burning reputation with every send. Always verify lists with EmailListVerify, Debounce, or similar before sending, even if the leads are fresh. Dead addresses accumulate faster than most people realize.

What's the exact symptom you're seeing? Emails going to spam, getting blocked entirely, throttled by your provider, or bouncing at high rates? The fix depends on which one.
