New Contabo IP's Are Blacklisted

Many people have highly recommended Contabo VPS server for bulk emailing. So I just opened a new account couple days ago. I purchased an extra IP as well. I checked out their brand new fresh IP addresses using MXToolbox, and the results came back listed on UCEPROTECTL3. Support told me they are trying to resolve??? My question is will this IP blacklisting by UCEPROTECTL3 compromise my own reputation emailing efforts (using MailWizz) as far as going into spam now?

Any other high recommendations for SMTP server?

Hi Scott,

I just I am also having this same issue on 1-21-2021.   However, I purchased my IP addresses months ago with Contabo.

On 1-16-2021 and 1-17-2021 I tested my email campaign on GMASS and was almost getting into all the primary inbox's.  I sent my first ever campaign (20emails) out on the 18th  and second campaign(40 emails) on the 19th.   I got a lower open rate on the 19th and thought that was weird.  I did another test run campaign again on GMASS on the 2oth with the same email template that was getting me in the primary inboxes.  In GMASS I found almost all went into the Spam Box.

I contacted support@h-educate and Abdallah mentioned I just need to continue warming up my postal SMTP and continue on building the reputation in order to get into primary email boxes.

So I sent out another campaign yesterday the 22nd but only using 24 emails and by later today CST I have 12 opened/read emails according to Mautic.  So as far a compromising my reputation I am not sure I have because apparently in Mautic people are opening my emails.

I myself will also reach out to Contabo to help push this concern of ours.

I hope this gets resolved soon.

Hi Hassan and Scott,

 

I thought I would try to help in this matter of frustration that some might be having with Contabo IP being blacklisted.

I have researched  Uceprotect.net to get more further information.  Scott you should do this to get further information if needed to. Here is the website http://www.uceprotect.net/en/index.php?m=7&s=0

There at the website you can type in your personal IP address to get the explanation I am about to provide here:

NOTE: Here's what it is telling me.  Sorry for the long paragraphs but I could not attach pictures to show of proof.

 

There are 3 levels of being blacklisted according to this website.

Level 1 (Single IP) meaning your personal IP address

Level 2 (Network the IP belongs to)  Contabo

Level 3 (The Reputation of ASN 51167 | CONTABO, DE)  Meaning the providers reputation

 

From what I am looking at the Level 1  my personal IP address is not blacklisted and is considered risking level as low. Level 2 I'm still not seeing anything pertaining to me either.

However this is where it gets messy.  I provided this information to hopefully help anyone in this situation.

 

" <b>What does it mean to be listed at the UCEPROTECT-Level 3?</b>
UCEPROTECT Network operates three levels of blacklisting, so our users can make the decision how strong they want to filter.
While UCEPROTECT-Level 1 lists single IP's only, UCEPROTECT Level-2 escalates and lists spammy allocations.
UCEPROTECT-Level 3 is the highest possible escalaion, complete Autonomus Systems (AS) get listed at Level 3 if there were too many spamming IP's (listed in Level 1) originating from said AS within the last 7 days.
If the provider harbours too many spammers and only has one ASN (Autonomus System Number) that logically means:
All IP's of said provider get listed at Level 3 then.
Click here to see the Policy for UCEPROTECT-Level 3

 

Here's what else it says

<b>"As you should know now: It is not you, it is your complete provider which got UCEPROTECT-Level 3 listed.</b>
So my  IP 207.180.224.168 that I purchased from Contabo was NOT part of a spamrun, but since I am the one that has freely chosen this provider (Contabo)

By tolerating or ignoring that your provider doesn't care about spammers you are indirectly also supporting the global spam with your money.
Seen from this point of view, you really shouldn't wonder about the consequences."

<b>"Therefore we recommend:</b>
Please send a complaint to your provider and request they fix this problem immediatly.
Think about this: You pay them so that you can use the Internet without problems"

"If they are ignoring your complaint or claiming they can't do anything, you should consider changing your provider.
There are currently about 105,000 providers worldwide, but only a few hundred make it to get listed into UCEPROTECT-Level 3."

 

"According to the statistics measured against the mail flow of several national authorities in Germany, Austria and Switzerland, those few providers which often end up in our Level 3 are responsible for 50 - 75% of all global spam, while almost no real mail came from their networks and ranges."

 

We often get to hear the argument: My provider is so hugh, and they have so many home users, it is almost impossible that they can create effective measures to prevent spam.
This statement is simply wrong and an excellent good example for a large but clean provider is DTAG (ASN 3320):

DTAG has about 34 million IP's and the majority of their customers are likely to be home users.
In spite of this size you can nowadays see almost no spam from the DTAG address space.
Let's see DTAG (ASN 3320) here.

An even more stunning example for a large but clean provider is Microsoft (ASN 8075):

Microsoft has about 33 million IP's and they are likely running Windows, which is a primary target for cybercriminals, due to its high distribution.
In spite of this facts you can nowadays see almost no spam from the Microsoft address space.
Let's see Microsoft (ASN 8075) here.

<b>The question must be: If big providers like DTAG and Microsoft can so effectively prevent that their customers are sending spam, why can your provider not also do so?

</b>The simple answer is: The Abuse Departements of providers NOT listed in our Level 3 are doing an excellent job, while those listed do not.

If your provider really wants to stop the excessive spam coming from their ranges they would simply install some preventive measures.

This 4 little steps would make the difference - and could be done in less than one hour.

<b>Can't you make an exception for me?</b>
We never make exceptions. Requests are futile. Only your provider can fix this problem.
Anyway our system respects IP's which are registered at ips.whitelisted.org, these are excluded from Level 3.

<b>How can my providers total IP-space be removed from UCEPROTECT-Level 3?</b>
After your provider has fixed those excessive spam problems, UCEPROTECT-Level 3 listing will be removed automatically and free of charge as soon as the causal Level 1 listings will expire and decrease below Level 3 escalation limit.
Every IP temporary listed at Level 1 expires 7 days after we have seen the last abusive action originating from there.
Automatic expiration is free of charge, because it does not require manual work.
If your provider don't want to wait for free expiration, they can optionally order expedited express delisting, which is charged a total of  for all IP's and ranges under their ASN.
Orders for expedited express delisting are processed by external service providers, therfore it cannot be offered for free.
Please note that payment is not a solution, but limiting abuse is.
Therfore it is important that those excessive spam problems which have caused the listing at Level 3 are fixed in first place, otherwise your providers complete IP-space might end up in Level 3 again within a short timeframe.

 

I hope this clarifies all we are going though.  I do not know how much of an effect this is having on my IP address but I have sent more Warm Up Campaigns  for my local business in the town I live and my last 3 campaigns ( sending 50-100 emails) have less than a 5% open rate.

This could be that I need to still develop my reputation with my campaigns and or other.

 

Thank you Hassan for all your help and guidance.

Hey guys,

I just contact Contabo and below is their respond.

Thank you for your e-mail.

UCEPROTECT recently changed their listing policy and this caused IP addresses from our network to be listed in their so-called "Level 3" blacklist. We started analyzing the background of this listing immediately upon notice and implemented measures to solve the cases causing this listing right away.

As we do not have any influence on the delisting process as such it is not possible for us to give you an estimated time for the delisting at UCEPROTECT. Therefore, we also investigated the consequences of a Level 3 blacklisting at UCEPROTECT ourselves:

Big mail providers (e.g. Gmail, Hotmail, Yahoo) are not using the UCEPROTECT filters at all and e-mails to those providers are therefore not affected by this listing.

Even smaller mail servers using the UCEPROTECT filters will most likely not include the Level 3 rules since UCEPROTECT themselves consider the Level 3 filter as too strict.

While we are still working on a final solution regarding the UCEPROTECT listing, the blacklisting as such should not have any impact on regular mail delivery from your server. Even though mail servers with a too strict filter setup may be affected, the current listing can be considered uncritical for general mail delivery.

If you have any questions or need help, please do not hesitate to contact us.

Hi Wizzo,

To answer your reply NO I do not believe I am inboxing.  Although in the beginning I was inboxing especially in my GMASS tests I ran multiple times.   Also I was getting between a 30%-63.5% open rate when I just started my email campaign 3 weeks ago according to Mautic. Then all of a sudden one small email campaign I sent  I barely had any emails opened.   So I checked with GMASS again to see if I was still going into the primary inbox and all of a sudden all everthing is going into spam. SO what happended??? I dont know and I was frustrated too.  The last 5 email campaigns I have sent were  total of 715 emails sent locally to my area and in total only 4 opened emails according to Mautic.  I know in one of Hassan's YouTube videos he talks about that sometimes you just have to keep warming up your SMTP until you start getting into inbox.  I hope Contabo customer support is right about this matter and that I just need to be patient and hopefully my emails will start going back into the primary inbox like they were before.  If anything changes I will try to do my best to update here.

Hi Hassan,

As you stated above and I quote "Hi friend, it’s ok. you can remove the blacklist by contacting the blacklist company and don’t worry to uch about this."

 

On the UCEPROTECT website it says that if we are blacklisted on level 3 then we cannot be removed individually and it has to be the company whos providing the IP address for us individually to make the correction.  I just wanted to inform and help out.  Thank You

Hey @Dagoat3319,

Noted..

I was try to test just my own email then i see it's landing on spam folder. Then i check IP Blacklist and looks like i was listed in 2 Blacklist site which is UCEPROTECTLV2 &3 and SEM FRESH.

SEM FRESH which is for new domain name. So means you need to have a domain registered for more than 5 day or 15 day or 30 days before you start sending email.

So still i did not start warmup the ip address i will wait for 30 Days to get removed from the second blacklist(SEM FRESH) and then try what contabo support say if i can inboxing and warm up the ip address.

Hey Wizzoo,

Thank you for responding.  I am aware of SEM FRESH but now how they operate so I thank you for informing me.  To let you know before I started my email campaigns I did to wait over a month before I sent emails with my new domain, HOWEVER, I do not recall ever being blacklisted from the beginning.  I could be wrong but the reason why I waited a month before I sent emails was because I got a little busy and was trying to perfect my email page in order to pass the GMASS inbox testing.

Best of luck us.  I will continue to keep you informed

@longvanren The UCEPROTECT3 will not affect small mail servers. You can work with Contabo IPs, we tested them.

@abdallahtaleb Assalam Mr. Abdallah,

Thank you for the information. I hope you can help me on how to use the Contabo IPs, because I have been using them and all my emails end up in our contacts spam. It is UCEPROTECT that blacklisted our IP at level 3.

Regards,

Yakubu.

@yhayim This blacklist does not affect small mailing servers. Your emails are ending up in spam due to reputation.

@abdallahtaleb Thank you so much.

If I get you right, the UCEPROTECT is not what is causing our mails to end up in spam.

We should now focus on getting better reputation to ensure that future mails hit the inbox of our customers.

Right..?

@yhayim Yes this is right, UCEPROTECT3 is not the issue. Focus on getting better reputation.
