How to stay off Email Blacklists?
Two Ways to Stay Off Blacklists
Blacklists use spam traps and track senders as possible sources of spam. A spam trap looks like a real email address, but it doesn't belong to a real person and can't be used for any kind of communication. Since spam trap addresses can't opt-in to receive an email, the only way one could end up on your list is if you're not maintaining healthy lists, or you're not abiding by the rules of permission-based email marketing.
1. Use confirmed opt-in and opt-out features and avoid purchasing or rent recipient lists.
These lists are loaded up with various unpalatable things, much like a nutty delight. We're talking invalid addresses, immaculate spam traps that were scratched from a site, and old addresses that may now be a spam trap. Also, recipients on these lists have not finished a pick for your email messages, which thus will create higher complaint rates. High complaint rates feed into various blacklists that track user spam and abuse complaints, so it's ideal to avoid any bought list.
2. Keep your technical standards high:
• Set standards and IP checks to regulate how articles are e-mailed from your domain. • Keep your e-mail server functioning efficiently. A recipient’s infected device can make you responsible for spreading a virus. • Make sure that comments to a blog post about one of your articles don’t reflect back to your server.
