We have our own email server that sends 3k cold emails per day and has 100/100 reputation score 🤩
A lot of people have asked me about our setup so here it is
Step One 💻 Create a VM on your preferred cloud service and use docker to bootup an email server using Mailcow
Step Two 🛜 Buy an alternative domain because you don't want to run unnecessary risks and destroy the reputation of your main domain. (We bought podsqueeze .co)
Step Three 🥶 Warm up your server using a service like MailReach (we highly recommend this one). Just keep it on because it will always be working for you
Step Four 🔧 Setup SPF, DKIM, and DMARC on your domain provider
Step Five 📋 You want to reduce the chances of your emails being marked as spam at all costs! So you need to create a highly targeted email list of people that will be happy to read your email. After having your list you can use a Email List Validation to remove all the potentially broken emails...
Step Six 📝 Spend some time creating the best cold email possible. The words you use can actually determine if your email is considered spam or not. MailReach has a Spam Checker service that I highly recommend you to test multiple variations of your email.
Step Seven 🤖 Start sending your emails and try to replicate human behavior. Start slow with one or two emails per hour and slowly increase that number. Make sure to implement a random sleep in between each send.
And that it is 🙂 After that is just a matter of monitoring your score and answer to all the emails you get.
