How to Verify a Mail SMTP Server 's Is New & Fresh ?

Server 's Is New & Fresh ( Server's IP Clean - Server's IP Clear - Not Blacklist ). That means the server's IP has never been used to send mail

We check SMTP Server here: https://www.blacklistmaster.com

IPv4 IPv6 or domain name: Name Server ( For example name server is mail.ordersmtp.com )

Select: IP blacklists

If all anti-spam organizations show Not Listed or Timeout. This means SMTP Server's ip is new and fresh ( Server's IP Clean - Server's IP Clear - Not Blacklist )

The quality of SMTP Server is divided into 3 types

TYPE 1: SMTP SERVER ( Spamhaus: clear )

This is the type of SMTP Server's ip in the backlist of some anti-spam organizations. However ... the server's IP has not been blacklisted by Spamhaus yet

Email Delivery Rate:

+ This type of SMTP ( Spamhaus: clear ) has a weak delivery rate. Using SMTP ( Spamhaus: clear ) has a very high delivery rate with domain mail with no firewall or weak firewall. 

+ This type of SMTP (Spamhaurs: Clear) it deliver on Spam Yahoo / AOL. Because Yahoo / AOL has a spam filter system ... only a few mails are sent to Spam Yahoo / Yahoo for the first time. The rest are blocked by the spam filter system ... so they don't deliver

Advantages of this type of SMTP:

This type of SMTP can send bulk mail with a large number of emails per day. If you know how to filter mail list there is no firewall or weak firewall. Inbox rate will be very high. About 80%.

However ... if you don't know how to filter the mailing list. If you use this type of SMTP ( Spamhaus: clear ) send bulk email with mail list is Domain Mail ( Compamy Email ). We think the deliver rate is around 30% - 50%

Disadvantages of this type of SMTP

This is the type of SMTP generated from the dedicated server without limits. However we can only buy new domain to create SMTP. Domains that don't have a high reputation will reduce the delivery rate.

For the above reasons ... we recommend that you do not send bulk mail with a strong firewall and spam filtering system. 

Email list with strong firewall and spam filtering system - Usually the mail service of large companies

Gmail - Outlook - Yahoo - AOL - Office365 ( Domain Mail ) - G Suite ( Domain Mail ) - Cpanel ( Domain Mail ) - Yandex - Mail.com .. etc

TYPE 2: New & Fresh SMTP SERVER ( Server's IP Clean - Server's IP Clear - Not Blacklist )

+ This type of SMTP Server is not blacklisted by any anti-spam organization. That means Server's IP is new & fresh  ( Server's IP Clean - Server's IP Clear - Not Blacklist ).

Email Delivery Rate:

This type of SMTP Server has a higher delivery rate than type 1 ( SMTP - Spamhaus: clear ). However ... You should also only send email lists with no firewalls or weak firewalls.

Depending on the country of the SMTP Server. SMTP has a delivery rate with a strong firewalled mailing list.

For example: USA EU SERVER - Easy Deliver Spam Gmail - Yahoo - AOL | Spam or Not deliver Office365 - Outlook - Hotmail

                      Japan - Thailand - Singapore- Asia - Easy Deliver Spam Office365 - Outlook - Hotmail - Yahoo - AOL | | Spam or Not deliver Gmail.

We recommend using SMTP for bulk email sending with mail lists that do not have firewalls or weak firewalls. 

Most domain email companies are emails with weak firewalls. They buy dedicated servers and their technical staff install email domains in bulk. The cost will be very cheap.
