Before you email

Before you email

Hope this article is useful to our readers. We discuss a few things you must do to ensure before sending emails to someone.

These are common mistakes from many. Even for the service providers, it is common to find these mistakes for those incoming emails.

I’m listing them here and you can check if you have done these or you should you quickly rectify them.

a. Find out your SMTP Mail server IP address, It is important to know which IP address your emails are sending out from.

b. Once you know the outbound IP address. Go to MXtoolbox https://mxtoolbox.com/blacklists.aspx to check if your outbound IP address is blacklisted by the popular RBLs.

Make sure your IP address is not blacklisted, otherwise your emails might be rejected at your recipients’ mail server.

c. Now, we make sure this outbound is listed in the DNS SPF record using this tool https://mxtoolbox.com/spf.aspx.

d. PTR record or rDNS on your outbound IP address. Using this https://mxtoolbox.com/ReverseLookup.aspx

e. You can enhance your email delivery by adding DKIM. DKIM is a kind of signature acts as the emails are sent by the sender via the permitted mail server. Most tools online are not friendly for the layman. Just write to our support team with the email address you want to check, our engineers will find out for you.

f. DMARC – This is yet widely practised and this will not work if your recipient’s mail server does not do a DMARC check. DMARC prevents spoofing and phishing like you have SPF, DKIM or both. DMARC does a bit more, like sending reports and action published in the DMARC record.

We encourage domain to publish DMARC and the above to protect your business and brand.

TTFB vs disk speed

While I’m doing some researches. I bumped into a new player for Cloud servers in Singapore. They are quite similar to the Linode and Digital Ocean.

The price structure is alike. However, they have the Windows version and of course, you pay more for the number of CPU core purchased.

They have claimed their disk read and write speed are faster than Digital Ocean and others. So, I’m keen. Since that, I have been using Linode for my disaster recovery service and this could be my alternative. Hence, I have signed up.

The entire process is no stranger to me since I’m quite familiar with Linode and Digital Ocean. The Cloud server was created quickly but I have to top up at least USD 10 to remove my trial. During the trial, you are not able to update rule in the firewall section.

I planned to DR my website at first but I have taken the opportunity to see if I will able to speed up my website since the disk read and write are faster.

I have used the under-construction template as my test page, and I make sure my SSD VPS is identical to my new cloud server. Both have gzip enabled and HTTP/2.

However, the result is a bit disappointing. Vastspace’s SSD VPS still load better. Frankly speaking, you cannot tell the differences with your naked eyes. Until you use tools like GTmetrix or the speed test at Pingdom.

The VPS with the IP starts with 103.237.X.X is sold by Vastspace. This is the original VPS, not the high-performance VPS. I’m happy to see Vastspace’s VPS outperforms in TTFB despite the speed is better in the disk drive as claimed.
