Beyond Blacklists: Why Anti-Spam Filters Aren't Enough for B2B Senders

Imagine you are in charge of a sales team. One of your BDRs, let’s call her “Jen,” goes to send her emails today, but she can’t. 

Same list, the same tools, same copy as always, but the email account is suspended this time.

Other BDRs are unaffected. Just Jen. Weird. You ask your IT team, your CTO; you ask everyone – “What is happening?” 

The same email list, tools, and email copy she's been using suddenly trigger an unexpected obstacle: Google's anti spam filters. 

While fictional, this scenario reflects a real challenge faced by countless B2B senders today. Email deliverability, the ability to get emails past spam filters and into inboxes, is crucial for B2B success. Yet, relying solely on avoiding blacklists, which simply identify known spammers, leaves B2B senders with limited control and facing the potential of arbitrary account suspensions like Jen's.

This article explores why anti spam filters, despite their vital role in combating spam, have limitations and why B2B senders need a more comprehensive approach to navigate the complexities of email deliverability in the modern age.

What are The Challenges of Anti Spam Filters for B2B Senders

While anti spam filters are critical in safeguarding inboxes from malicious content, they can present significant challenges for B2B senders. Here's why:

1. Lack of Transparency 

Anti spam filters operate like a black box. B2B senders have little insight into the specific criteria used to label emails, making diagnosing and resolving potential issues extremely difficult. Essentially, it's an attempt to improve your email delivery without understanding what is triggering the filters in the first place. This lack of transparency can lead to frustration and unnecessary effort as B2B senders grope in the dark and mindlessly adjust content and strategies.

2. False Positives

B2B senders, even when they have good intentions and adherence to best practices, can fall victim to false positives. Overly aggressive anti-spam algorithms can sometimes misinterpret legitimate content as spam, leading to perfectly good emails ending up in the spam folder or, worse, resulting in account suspension. This can significantly disrupt outreach efforts and damage sender reputation, impacting future deliverability rates.

3. Lack of Control and Predictability

B2B senders have limited control over the intricate workings of anti spam filters. This lack of control translates to unpredictable deliverability. Even emails that have historically performed well can suddenly get flagged, causing uncertainty and hindering campaign effectiveness. B2B senders need a degree of predictability to plan and execute successful email marketing strategies, and relying solely on anti-spam filter whimsy makes it nearly impossible.

4. Potential for Account Suspension

Repeated triggering of anti spam filters can lead to the most severe consequence: account suspension. This scenario shuts down all email-sending capabilities, effectively disabling B2B outreach efforts and potentially causing significant disruption to ongoing business communication. Imagine an entire sales team unable to send emails to prospects or clients due to an unforeseen anti-spam filter issue. Such a situation highlights the need for B2B senders to go beyond simply avoiding blacklists and look for more comprehensive solutions.

These challenges underscore the limitations of relying solely on anti spam filters for B2B email deliverability. Fortunately, there are strategies and solutions available to B2B senders to navigate these complexities and achieve predictable and reliable email delivery.

The Limitations of Blacklists

In the fight against spam, blacklists have long served as a first line of defense. These databases contain known spam sources, such as IP addresses or domain names. Email providers use them to block emails originating from these blacklisted sources automatically.

While blacklists offer a certain level of protection, they have significant limitations:

1. Not a Foolproof Solution

Blacklists function by maintaining a list of known spammers, typically identified by IP address or domain name. However, spammers are constantly evolving their tactics. They can easily change their IP addresses or domains to circumvent detection. This renders blacklists ineffective in stopping new and emerging spam threats.

2. Risk of False Positives

While aiming for accuracy, blacklists are not infallible. Legitimate B2B senders can sometimes be mistakenly blocked through accidental association with known spammers sharing the same IP address or hosting provider. This can lead to significant disruptions in email outreach, impacting brand reputation and customer communication.

3. Scope

Blacklists primarily focus on identifying known spam sources, neglecting other factors crucial for email deliverability. This approach leaves them vulnerable to new and emerging spam tactics, allowing novel forms of spam to bypass detection altogether. B2B senders relying solely on blacklists remain exposed to these more recent threats.

Yes, blacklists offer a basic layer of protection, but they are not a foolproof solution for B2B email deliverability. Their limitations necessitate a more comprehensive approach that also considers sender reputation, content optimization, and engagement metrics to ensure consistent and reliable delivery of B2B emails.

Moving Beyond Anti Spam Filters – ho to take Control of Your B2B Email Deliverability

While anti spam filters are essential for a healthy email ecosystem, they can leave B2B senders at the mercy of unpredictable deliverability and the constant threat of account suspension. But there are ways to take the wheel and confidently navigate this landscape.

1. Permission 

Remember Jen, the BDR whose account got suspended? One way to avoid a similar fate is to build an engaged email list through opt-in processes. This means acquiring explicit consent from recipients before adding them to your list. Think of it like inviting them to your house party, not ambushing them with an unwanted flyer on the street. 

This approach fosters trust and legitimacy, reducing the likelihood of triggering spam filters. Opt for clear and concise signup forms, offer valuable content in exchange for subscriptions, and always obtain explicit consent before adding individuals to your list.

2. Content

Creating high-quality, relevant content tailored to your target audience's needs and interests makes all the difference. Engaging content not only increases open rates and click-through rates but also signals legitimacy to email providers, leading to improved deliverability.

Avoid spammy tactics like excessive caps lock, misleading subject lines, or irrelevant attachments. Focus on providing valuable information, addressing pain points, and offering solutions that resonate with your audience.

3. Sender Reputation

Maintaining a good sender reputation is like having a clean record with the local authorities. It demonstrates responsible email practices and increases your chances of reaching your target inboxes. This involves consistently sticking to best practices: only email opted-in recipients, avoid spam triggers, and keep your bounce rates low.

Monitor your sender reputation scores, and if you see any red flags, take immediate action to address them. Think of it as keeping your house party fun and responsible, avoiding any shenanigans that might get you shut down by the email "authorities."

4. Specialized Platforms: Your Email Delivery Allies

Several email-sending platforms are designed specifically for B2B outreach. These platforms offer features like advanced sender reputation management tools, email deliverability monitoring, and campaign analytics. They become your allies in navigating the complexities of email deliverability and achieving optimal results.

Explore reputable platforms that align with your specific needs and budget. Consider them your consultants, helping you ensure your B2B email outreach is successful and reaches the right audience.

By implementing these strategies and exploring alternative solutions, you can move beyond anti spam filters' limitations and control your B2B email deliverability. This empowers you to reach your target audiences effectively, build stronger relationships, and ultimately achieve your B2B marketing goals.

While anti spam filters are essential gatekeepers, they can leave B2B senders helpless. But there's hope! You can take control and reach your target audience by building trust with opt-in lists, crafting engaging content, and keeping your email house in order.

Remember, the key is a comprehensive approach beyond simply avoiding spam filters.

Founded by chef David Chang, Momofuku is a renowned culinary brand with a nation-wide presence, including restaurants and an online store with delicious goods. They ran into an issue with their email sending – high bounce rates and blocked sending.

With hundreds of thousands of people on their email lists eager to stay informed, and an impeccable reputation to uphold, Momofuku wanted to nip this problem in the bud quickly.

  • Momofuku reached out to Senders to run a diagnostic test on their sending infrastructure and find the root cause
  • Senders deliverability experts discovered an issue with their DMARC, which was preventing emails from being sent, as their WordPress wasn't aligned with their SPF
  • Senders provided the most effective solution helping Momofuku restore safe sending, and suggested next steps to ensure everything keeps running smoothly on their end
  • The client reported that Senders helped identify the problem and got them back on track 

Up for coffee with a health kick, sans the jitters? Try Everyday Dose – a brand on a mission to provide coffee lovers with a healthy alternative packed with all kinds of goodies. The Founder, Jack Savage, learned through personal experience that we needed an option that doesn’t lead to a slew of possible side-effects. That’s how this mushroom-based blend with nootropics and collagen protein came to be, helping boost focus, energy, and reduce stress in one go.

The Everyday Dose team prides itself on excellent customer support, in addition to their delicious set of products. So when they spotted DNS propagation issues setting up their customer experience platform, they reached out to Senders to find the best way to sort it out.

  • Senders deliverability experts confirmed the problem the team at Everyday Dose initially diagnosed
  • To enable healthy DNS propagation, the Senders team helped clean their DNS registrar of old DNS records that were causing issues with propagation
  • The client reported they were now able to set up their DNS correctly, enabling them to run their platform smoothly

While many follow the latest marketing fads, there are businesses that support their clients with impactful, data-driven strategies for long-haul success. One such business is Influence to Action, creating sales, marketing, and leadership strategies that provide lasting value to growth-centric B2B companies. Both their turnkey and “done with you” services are built to ensure measurable, tangible results, and come with ample flexibility to adapt to the company they’re meant to serve.

Naturally, they wanted to make sure their email sending infrastructure was set up correctly, to protect their reputation and successfully reach their recipients. Our deliverability team worked with the client’s team on:

  • Aligning the client’s three domains with Amazon to make sure they are compatible and optimized in order to integrate with Amazon’s system.
  • Setting up a proper DMARC policy to protect their domains against unauthorized use and phishing scams.
  • Enhancing email deliverability as well as security, so that each email sent from these domains can be properly authenticated and more likely to land in the right inbox.
  • As a result, the client can protect the reputation of their business and domains, while safely sending out their email campaigns.

Sometimes the sheer number of options of any product can be daunting – how on earth do you pick the right one? This is especially true with supplements, as we can find them just about anywhere, but we can rarely understand a third of the ingredients listed. Unlike most, Physician’s Choice provides supplements with pure, potent ingredients that work. No fillers or “proprietary” blends with unidentified ingredients. They do the research, so you don’t have to.

Integrity and transparency are part of their core values, so when their team ran into sending issues, they were referred to Senders.

  • The client’s team spotted issues with DMARC failures in Google Postmaster
  • The Senders deliverability team worked with the client to update the DMARC configuration to enable report collection
  • The client is now able to obtain detailed reports to diagnose the exact causes of the failures and prevent them in the future with proper DMARC setup
