Understanding Cold Email Deliverability in 2024

What is Email Deliverability?


Email deliverability is the ability of your messages to land in your recipients’ inboxes, not their spam folders. This metric is especially critical for cold emails, as it directly influences engagement, response rates, and your overall campaign success.

Common Issues Affecting Deliverability Today


Spam filters, sender reputation, and stringent policies from email service providers (ESPs) are major hurdles. Poorly executed campaigns often lead to emails being blocked or ignored, reducing the effectiveness of your outreach.

Why Microsoft Email Deliverability is a Challenge


Microsoft services, including Outlook and Office 365, employ some of the toughest anti-spam measures. Even with professional setup and warm-up practices, marketers often struggle to get past Microsoft’s defenses, significantly lowering response rates.

Email Providers and Their Deliverability Rates

Microsoft: The Struggles and Solutions


Sending to Microsoft-based inboxes can yield poor results, with marketers often reporting just one demo booked per 1,000 emails sent. For now, it’s better to deprioritize Microsoft inboxes and focus efforts elsewhere.

Google Workspace: Your Best Bet for Success


Google Workspace accounts offer a much higher success rate, with deliverability often exceeding 70%. This makes it the most reliable option for cold email campaigns. Businesses are encouraged to set up multiple Google Workspace accounts to maximize outreach efficiency.

Custom SMTP Providers: When and How to Use Them


Custom SMTP providers like Mimecast or Proofpoint can be useful for niche campaigns. While they may not match Google Workspace’s performance, they can outperform Microsoft in specific scenarios, particularly when targeting non-standard email platforms.

Avoiding Microsoft Email Challenges

Why Avoiding Microsoft Outlook is Critical


Outlook accounts, even paid ones, present numerous challenges due to Microsoft’s strict spam rules. By avoiding these inboxes, you can allocate resources to more promising opportunities and improve your ROI.

Tools to Identify Prospects’ Email Providers


Platforms like Clay and Apollo can help you identify your prospects’ ESPs at scale. For instance, Clay allows you to check thousands of email domains for as little as $1 or even for free if you have a Clay Pro plan.

Strategies for Redirecting Efforts Towards High-Yield Providers


Focus your campaigns on Google Workspace and other high-performing ESPs. Avoid Microsoft accounts by filtering prospect lists early in the process, ensuring your efforts target inboxes with better deliverability rates.

Optimizing Your Email Infrastructure

How to Diversify Email Sending Platforms


A diversified infrastructure ensures better deliverability and scalability. Use a mix of Google Workspace accounts and dedicated SMTP providers for the most reliable results.

Setting Up More Google Workspace Accounts

Given Google Workspace’s high deliverability rates, businesses should prioritize creating additional accounts to handle campaign volume. This investment can significantly boost response rates and conversions.
Testing Dedicated SMTP Providers for Improved Outcomes


SMTP providers like MailReef or MailScale can complement Google Workspace setups. Testing various providers allows you to determine which ones offer the best results for your specific audience and campaigns.

Building Highly Targeted Cold Email Campaigns

The Role of Market Research in Campaign Success


A well-researched campaign begins with identifying your ideal customer profile (ICP) and analyzing their preferences. This foundation ensures that your outreach is relevant and impactful.

Using AI to Sub-Niche Your Target Audience


AI tools like ChatGPT or Clay can help refine your audience by sub-niching based on industry, company size, or specific needs. For instance, targeting "automotive dealership software companies" rather than generic "tech companies" can dramatically improve engagement rates.

How Personalization Can Skyrocket Positive Replies


Personalized emails resonate better with recipients. AI can assist in crafting tailored messages by analyzing company data and generating relevant snippets that make your emails stand out.

Step-by-Step Campaign Execution Process

Identifying the Right Domains for Your Target Audience


Start with a list of 1,000 domains that align with your ICP. Use tools like Apollo to extract data about these domains, including their ESPs and company details.

Checking Email Providers Before Campaign Launch


Upload your domain list into tools like Clay to identify the most common ESPs in your market. Avoid Microsoft-heavy markets and focus on prospects using Google Workspace or custom providers.

Programming AI Agents for Enhanced Lead Qualification


AI agents can streamline the lead qualification process by identifying key roles within companies. For example, you can program an AI agent to find founders, general managers, or decision-makers, ensuring your outreach reaches the right people.

Scaling Campaigns with AI and Automation

Benefits of AI in Cold Email Marketing


AI reduces the manual effort required for prospecting and personalizing outreach. From identifying target companies to writing email snippets, AI tools can save time and improve accuracy.

Building AI-Powered Agents for Role Identification


AI agents can efficiently locate and extract specific roles from large datasets, reducing the need for costly data providers. For instance, finding 2,500 leads using AI may cost as little as $6.

Using AI for Personalized Email Snippets at Scale


Automate the creation of custom email lines by programming AI with relevant prompts. These personalized messages can significantly increase response rates by demonstrating a genuine understanding of your prospects’ needs.

Cost-Effective Tools for Cold Email Outreach

Affordable Solutions for Lead Generation


Tools like Apollo, Clay, and Pandamatch offer cost-effective options for building and managing lead lists. By combining these platforms with AI, you can optimize your outreach strategy without overspending.

Automating Processes with Clay, Apollo, and More


Automation tools streamline workflows, from prospect identification to campaign execution. This efficiency allows you to focus on strategy rather than repetitive tasks.

How to Save Time and Money with AI Agents

AI agents can perform tasks traditionally handled by large teams, such as role identification and email personalization. By integrating AI into your workflow, you can achieve better results with fewer resources.

Recap: Best Practices for Cold Email Success in 2024

  1. Focus on Deliverability: Prioritize Google Workspace for high success rates and avoid Microsoft for now.

  2. Leverage AI: Use AI to refine targeting, personalize emails, and streamline campaign processes.

  3. Sub-Niche Your Campaigns: Narrow your audience to specific industries or needs for better engagement.

Conclusion

Cold email marketing remains effective, but only for those who adapt to changing conditions. By prioritizing high-deliverability platforms, leveraging AI, and building niche-specific campaigns, you can stay ahead of the competition.
