What the experts say7Expert opinions
Expert from Email Geeks states that cold emails are essentially spam and will likely end up in the junk folder as intended. Furthermore, if a sender engages in spam practices, the resulting poor reputation can negatively impact even their legitimate business emails.
Expert from Email Geeks suggests that if the emails are really useful, to stop using a 3rd party tool and move it back to manual mail, using their own links, domains, and IPs.
Expert from Email Geeks says that the business choice leads down one of two paths: stop using third-party spammers, stop hiding behind different domains, and behave like a legitimate company, or go full-on criminal spammer. They add that the former is more viable long term and that delivery rates will worsen over time if current practices continue.
Expert from Spam Resource explains that you should ensure email addresses are gathered with explicit consent. Using purchased or scraped lists will almost certainly result in high spam complaint rates and damage your sender reputation. They share that building your list organically and confirming subscriptions are crucial for good deliverability.
Expert from Word to the Wise explains that a key step in diagnosing why your emails are going to spam is to test and monitor. Use seed lists and inbox placement tests to see how different mailboxes are treating your messages. Analyze the headers of emails that land in the spam folder to identify specific issues.
Expert from Email Geeks explains that the poster is likely dealing with generic corporate spam filters which are tightening and learning from B2C filters. These filters are responsive to their customers and will use fingerprinting to identify mail streams, impacting delivery decisions.
Expert from Email Geeks explains outbound emails could also be using the same IP address, so a different domain might not make any difference. Also the emails include ANY reference (e.g., image URLs, HREFs, email address in a salesperson's email footer) to your 'clean' domain, you're throwing it into the same reputation basket as the 'cold prospects' domain. I would also keep the 'cold prospect' stuff on its own ESP, far, far away from your 'clean' outbound traffic. Instead of _emailing_ cold prospects, think about using those lists to TARGET them on platforms like Facebook, LinkedIn, etc. where you can upload email/MD5 lists as your target audiences.
