Should I be concerned about the NoSolicitado blacklist for email sending?

Email marketer from Mailrelay explains that the NoSolicitado list is a real-time blacklist of IPs detected sending unsolicited email to domains hosted on their network and is particularly relevant if sending to Latin America, especially Argentina. Being listed can impact deliverability to those regions.

Email marketer from SenderVerify suggests that blacklists are a significant factor in determining email deliverability. Being listed can lead to emails being marked as spam or blocked entirely by recipient mail servers.

Email marketer from Email Geeks explains that the main concern with blacklists is their correlation with other blocks and whether mail providers share findings. For NoSolicitado, if delivery isn't affected, it's likely fine, but delisting can provide reassurance. Identify the cause of listing first.

Email marketer from Email Vendor Guide shares that it is important to monitor blacklists because it affects email delivery. If you send email it's essential to check key email blacklists frequently to ensure your sending IPs and domains aren't listed, indicating potential problems with your sending practices.

Email marketer from GlockApps shares the importance of checking your IP and domain reputation on blacklists as a key step in maintaining good email deliverability. They also suggest that being listed on multiple blacklists can severely damage your sending reputation.

Email marketer from Reddit explains that being on blacklists, even smaller ones, can negatively impact your sender reputation and cause deliverability issues. Although NoSolicitado might be regional, continuous listing could still signal broader problems to mailbox providers.

Email marketer from Email Marketing Forum suggests that if you're primarily sending emails to regions outside of South America, the NoSolicitado list may not be a top priority. Focus on larger, more globally recognized blacklists first.

Expert from Email Geeks shares that the best measure of whether to care about a blocklist like NoSolicitado is whether it stops your mail from being delivered, which your logs will indicate.

Expert from Word to the Wise explains the importance of monitoring your presence on blacklists, emphasizing that deliverability issues could arise if your sending IP or domain is listed. Proactive monitoring and addressing any listings promptly are key to maintaining good deliverability.

Expert from Spamresource.com responds to the question about being listed on a blacklist by providing a series of questions one should ask themselves to help determine the value or impact. Questions such as, "Do any of your customers use them to block mail?" are recommended.

Expert from Email Geeks responds that most providers do not secretly use public blocklists, with Spamhaus lists being the main exception. Actions leading to blocklisting can decrease reputation at providers, making it seem like they're using the lists, but delisting won't fix underlying problems.

Documentation from BarracudaCentral explains that if you're listed on their reputation block list, it means they have detected suspicious activity from your IP address. It is important to follow their removal steps to be removed and stop delivery issues.

Documentation from MultiRBL explains that RBLs (Realtime Blackhole Lists) and DNSBLs (DNS Black Lists) are essentially the same thing, lists of IP addresses involved in spamming or other malicious activities. If your server's IP is on such a list, email you send might be rejected by servers that use that RBL.

Documentation from Proofpoint explains that your IP address is your reputation and is important. They explain that poor sending practices can affect your reputation and also impact deliverability.

Documentation from Spamhaus explains that blocklists like the SBL can cause issues with email delivery if your sending IP or domain is listed. It is important to check and ensure your email practices are not triggering the list. If you are listed it may be impacting delivery.
