The Problem with Email Marketing

Email marketing is a sophisticated branch of your business activities and you can solve its main problem with free SMTP servers. You must master email marketing or your business will likely simply vanish without prosperity and you will have basically built a vanity business. However, if you get started with email marketing you can do it by learning the ropes for free with services from many competing companies.

Maybe you ask, “Why would they give it away for free? How can they make money that way?” They hope you will use their free tier of free SMTP servers to start making money with your business. After you have earned some money and have seen that your idea works and that you know how to make it work, they hope you will upgrade to their first paid tier and continue your success. The tools that come with these free options are enough to open up new possibilities for earning money with your business.

Deliverability without Free SMTP Servers

The first hurdle you must overcome with email marketing is deliverability. It is a problem because when you send a lot of emails the chances of one SMTP server receiving many of those emails is high. When you send too many emails to an SMTP server too quickly from the same email server (yours), the receiving server may flag your server as an origin of spam. That company which manages that email server may even submit your domain name and IP address to a blacklist. Many email servers are set to check and synchronize these blacklists with their local blacklist, effectively rejecting any emails at all from your IP address or domain name.

Solution in Free SMTP Servers

The best solution to this problem is to offload this function to a service that specializes in making sure other mail servers do not blacklist their SMTP (email sending) servers. Nevertheless, you still have to understand the limitations which that service places on your email campaigns and abide by them. That may include such requirements as sending rate limits (emails/hour or /minute or /day). Abiding by these limitations is much easier than managing the SMTP server technical and administrative headaches yourself.

Your time is too precious for this, because you need to be the CEO and run your own company. Instead, you should delegate it out to professionals in that field. The advantages of managing it in-house are so tiny when you do not have a very highly skilled professional on staff to take advantage of those few obscure advantages. Do not waste your time. Get into this review of free SMTP servers and get started making money from your email marketing.
