5 Most Popular Cold Email Infrastructure Tools (Quick Look)

‍

What Exactly is Email Infrastructure?

In simple terms, email infrastructure for cold emailing is the entire setup that ensures your emails land in the recipient's inbox and not in the spam folder. 

It's like building a road that your emails travel on. If the road is well-built and maintained, your emails reach their destination smoothly. If not, they get stuck or, worse, lost. 

Key Components of Email Infrastructure:

• Domain and Email Server: These act as your email’s home and road.
• IP Addresses: Choose between shared or private for your email sending.
• Authentication Protocols: SPF, DKIM, and DMARC work like security checks to verify your email's legitimacy.
• Reputation Management: Your domain and IP need a good reputation to ensure emails get delivered.

‍

Why is Email Infrastructure Crucial for Cold Emails?

Because when you and I send out cold emails, the recipients don’t expect them. This makes it more likely for these emails to end up in spam, especially if the email infrastructure isn't properly set up.

It’s like you’re knocking on a stranger’s door—if you don’t have a valid reason or a good introduction, the door might not open. Similarly, without a solid email infrastructure, your emails might never reach the inbox.  

5 Key Reasons Why Email Infrastructure is Crucial:

• Deliverability: Without proper setup, your emails might end up in spam folders, never reaching your prospects. A solid infrastructure ensures your emails land in the inbox, maximizing your chances of engagement.
  
  
• Scalability: As your outreach efforts grow, you need an infrastructure that can handle increased volumes without compromising performance. This means managing IP reputation, warm-ups, and proper throttling.
  
  
• Compliance: Adhering to regulations like GDPR and CAN-SPAM is easier with a well-structured email setup, avoiding potential legal pitfalls.
  
  
• Personalization: A good infrastructure allows for advanced personalization at scale, making your cold emails more effective by targeting specific pain points of your prospects.
  
  
• Tracking and Optimization: With the right setup, you can track key metrics like open rates, click-through rates, and responses, allowing you to continuously optimize your campaigns.

Getting your email infrastructure right is not just a technical requirement; it’s the backbone of a successful cold email strategy. 

‍

Complexities in Setting Up Email Infrastructure

Setting up email infrastructure isn’t just about picking a tool and going with it. It’s more like setting up a whole system. Here’s what you need to consider:

• Choosing Between Shared IP and Private IP: If you go for shared IPs, you’re sharing the reputation with other users. It’s like sharing a taxi; if one passenger behaves badly, it can affect the whole ride. On the other hand, a private IP gives you full control but requires you to build and maintain its reputation from scratch.
  
  
• Setting Up SPF, DKIM, and DMARC Records: These are like security badges that authenticate your emails. If you and I don’t set them up correctly, emails are more likely to be flagged as spam. And trust me, dealing with spam issues is a real headache.

• Ongoing Maintenance and Costs: Building a reliable email infrastructure takes time—setting up the domain, ensuring proper DNS settings, warming up the IP, and maintaining the domain reputation. It’s not a one-time setup; it’s an ongoing process.

So, if you're thinking about diving into cold emailing, remember that the success of your campaigns heavily relies on getting your email infrastructure right. 

It’s not just about sending emails; it’s about building a strong foundation that ensures those emails land where they should—in the inbox. 

Now, let's take a look at 12 things to consider when investing in an email infrastructure tool.

12 Things To Look Before Investing In Cold Email Infrastructure Tools?

5 Most Popular Cold Email Infrastructure Tools

1. Mailforge

Mailforge is a cold email infrastructure tool that provides a reliable and robust way to manage your cold email campaigns. The tool is well-known for its strong deliverability rates and user-friendly interface.  

Unlike some other tools, Mailforge focuses on simplifying the setup process while offering powerful features that help you scale your outreach smoothly. 

Key Features of Mailforge

• Email Tracking: Allows you to monitor who opens your emails and clicks on your links. This helps you understand which emails are performing well and which need improvement.
  
  
• Bulk Email Campaigns: Enables you to send emails to hundreds or thousands of recipients at once without compromising on performance or deliverability.
  
  
• Automated DNS/DKIM/SPF Setup: Automatically configures essential authentication protocols to ensure your emails are seen as legitimate, reducing the risk of ending up in spam folders.
  
  
• Detailed Analytics: Provides comprehensive insights into your email campaigns, including open rates, click-through rates, and response rates, allowing you to optimize your strategy.
  
  
• Domain Transfer: Offers a seamless process for transferring your existing domains, making it easier to manage multiple email campaigns from one platform. 

Mailforge Pricing

Mailforge’s pricing starts at $3 per month per mailbox, with discounts available for bulk purchases, making it a flexible option depending on your needs.

 While it might be slightly more expensive compared to other ESPs, its robust features, ease of use, and reliable deliverability often justify the cost. 

For Example:

Let’s say you’re a small B2B agency managing cold email outreach for multiple clients. You need to manage 5 different domains with a total of 50 email accounts to run targeted campaigns.

• Domain Cost: If each domain transfer costs $13 per year, the cost for 5 domains would be:
  • 5 domains x $13/year = $65/year
    
    
• Email Account Cost: Assuming you go for the bulk pricing option where each mailbox costs $2.50/month (since you’re managing 50 mailboxes), the total monthly cost for email accounts would be: 
  • 50 email accounts x $2.50/month = $125/month
  • Annual Cost for Email Accounts: $125/month x 12 months = $1,500/year

Total Annual Cost for Using Mailforge:

• Domain Costs: $65/year
• Email Accounts Costs: $1,500/year

Overall Cost: $65 + $1,500 = $1,565/year

With this setup, you’d have robust email tracking, automated DNS/DKIM/SPF setup, and detailed analytics for all your domains and mailboxes, ensuring high deliverability and efficient management of your cold email campaigns.

Pros and Cons of Mailforge

Pros:

• Robust Features: Provides comprehensive tools for email tracking, automated setups, and detailed analytics.
  
  
• Easy to Use: The intuitive interface makes it simple to set up and start running  campaigns, even for those who aren't tech-savvy.

• Good Deliverability: High deliverability rates help ensure your emails land in the inbox rather than the spam folder.
