Cold email campaigns, in essence, are about reaching out to people who've never interacted with you before. Imagine, you're a cybersecurity startup trying to break into a competitive market. 

You need to introduce your product to potential clients. Instead of waiting for them to find you, you take the initiative to reach out directly. 

With 80% of buyers preferring email contact, launching a cold email campaign seems like a no-brainer. The goal is simple: grab attention, establish a connection, and, ideally, turn prospects into clients. 

So you've just kicked off your most ambitious cold email campaign yet. But as soon as you start increasing your sends, your emails start landing in spam, and your deliverability tanks. Frustrating, right?

In this article, we're not just going to talk about scaling cold email campaigns. We're going to reveal the secrets of how to do it without sacrificing deliverability and explore how to avoid the common mistakes that can cost you a ton of time. 

Let’s dive in:

What are the Common Issues When Scaling Cold Email Campaigns?

Now, let’s talk about the hurdles you might face when you decide to scale your campaign. Scaling isn’t just sending more letters. It requires a strategic approach and careful attention to several key factors:

1. Contact List

‍If you plan to scale, you need a solid contact list. Poor segmentation or outdated email addresses can lead to your messages ending up in spam more often. Regularly verifying and updating your list is critical. 

2. Low Deliverability Rates

‍One of the most frustrating challenges of scaling cold email campaigns is watching your deliverability rates drop. A sudden increase in sending volume can cause emails to be flagged as spam.

So, jumping from sending a few hundred emails a day to thousands requires skillful management. A sudden increase in volume can impact your sender reputation and deliverability.

3. Poor Email Open Rates

‍Even if your emails land in inboxes, getting recipients to open them is another battle. Poor open rates are often linked to non-personalized content, irrelevant subject lines, or inconsistent sender reputations.

If you want people to actually engage with your emails and not just scroll past, you’ve got to focus on these things.

4. Personalization

‍As the volume of newsletters increases, it becomes harder to keep things personalized. And yet, personalized emails are much more likely to get a response.

For instance, personalized subject lines have an open rate of 35.69%, nearly double that of non-personalized ones at 16.67%. Using automated tools has to be balanced with high-quality content. 

Why Is Deliverability Important for Your Email Campaigns?

Deliverability is the percentage of emails that actually land in the recipient’s inbox. It’s influenced by several factors:

• Your domain settings;
• Your IP reputation;
• User engagement.

Deliverability isn’t a static metric. It needs to be constantly monitored and optimized.

If your emails aren’t reaching the recipient or end up in spam, all your effort and costs for creating content, segmenting your audience, and setting up automation go to waste.

The higher your deliverability, the more likely it is that your message will be read and could lead to the desired action (a sign-up, a purchase, or a request for more information). 

So, to keep your cold campaigns effective, you need to keep a close eye on deliverability and continuously adjust your strategies. We’ll discuss how to do that in the next sections. Stay tuned—there’s plenty of valuable information ahead!

Why Some Emails Land and Others Don’t: The Key Factors

To keep your cold email campaigns out of the spam folder, it's important to understand the technical details. Don’t worry, we’ll go through it step by step!

1. Email Authentication (SPF, DKIM, DMARC)

Let’s start with the basics—authentication. SPF, DKIM, and DMARC are the three key elements that will help keep your emails out of spam and boost your sender reputation.

• SPF (Sender Policy Framework). This is your email’s passport. It confirms that you’re authorized to send emails from your domain. You need to set up an SPF record in your domain’s DNS so mail servers know which servers can send letters on your behalf.
• DKIM (DomainKeys Identified Mail). This method adds a digital signature to each email you send. Mail servers check this signature to ensure that the email hasn’t been altered during transmission and that it indeed came from your domain.
• DMARC (Domain-based Message Authentication, Reporting, and Conformance). DMARC combines SPF and DKIM and helps set a policy for handling emails that fail authentication checks. You can also receive reports on how your emails are processed. This helps you better understand deliverability issues.

2. SMTP Configuration and Maintenance

The SMTP server (Simple Mail Transfer Protocol) is your email’s delivery system. Proper setup and maintenance are essential for good deliverability.

Make sure your server is configured to send emails only from authorized IP addresses and that it operates without issues. Regularly check the server for problems that might affect deliverability. 

How to Prepare for Scaling Your Cold Email Campaigns?

Before you launch a big campaign, getting everything ready is a must. It’s not just a checkbox. This all really matters. Here’s how to get started:

1. Email List Quality and Verification

First things first: make sure your email list is clean and current. Outdated or incorrect addresses can tank your deliverability.

Regularly scrub your list for invalid or non-existent addresses. This keeps you from sending emails to dead inboxes and helps cut down on unsubscribes and spam complaints.

Ensure your list only includes people who might genuinely care about your offer. Clear out old and inactive addresses to keep your resources focused.

2. Advanced Segmentation Strategies

With a clean list, it’s time to deal with segmentation. The more targeted your campaigns are, the better they’ll perform.

Interest-Based Segmentation

‍Split your audience based on their interests or needs. For example, if you offer various types of software, create segments for each type of users so you can send them relevant offers.

Behavioral Segmentation

‍Use data on how your subscribers behave to craft personalized offers. For instance, if someone has shown interest in a particular topic, send them more detailed content related to that interest.

3. Choose the Right Email Service Provider (ESP)

Next up, choose the right service provider.

Evaluate what features the ESP offers. Do you need built-in tools for automation, analytics, or A/B testing? Make sure the platform integrates well with your other systems.

Look for providers with a strong reputation and solid support. Feedback from other users and reviews can help you choose a reliable partner. Be sure to check reviews on independent platforms, not just the ESP’s own site.

4. Dedicated IP Addresses vs. Shared IP Addresses

When scaling, you’ll need to decide whether to use dedicated or shared IP addresses.

• Dedicated IP Addresses. These offer more control over your reputation since you’re not affected by other users’ behavior. This is a good choice if you have a high volume of sends and are prepared to invest in maintenance and setup.
• Shared IP Addresses. A more affordable option, but with less control. Sharing an IP with others means your reputation can be impacted by their activities. This might be acceptable in the early stages but requires careful management.

5. Creating a Warm-Up Plan

Now that you’ve got all the technical and organizational details sorted, it’s time to start warming up your campaign. You need to gradually increase your sending volume to avoid overloading the mail servers.

• Planning the Ramp-Up. Start with small volumes and slowly scale up. Keep an eye on your deliverability and engagement metrics so you can adjust your strategy as needed.
• Analysis and Adjustment. Regularly monitor your results and make adjustments. If you notice deliverability dropping or other issues arising, cut back on the volume and troubleshoot.

In short, preparing for scaling involves paying close attention to details. Data quality, infrastructure setup, and warm-up planning are all critical for a successful launch and scale of your campaigns.

6. Monitoring and Optimization

After you’ve kicked off your scaled campaign, the next key step is monitoring and optimizing. It’s not just about watching the numbers. The real goal is to actively work on making things better. Here’s how to do it right.

Key Metrics to Track

There are a few important metrics you should keep an eye on to see how your emails are doing:

• Bounce Rates. This covers both soft and hard bounces. Soft bounces might be temporary issues (like a full inbox). Hard bounces are permanent problems (such as invalid addresses). It’s important to spot the difference and act accordingly.
• Spam Complaints. This shows how many people have marked your email as spam. A high number of complaints can hurt your reputation and deliverability. If you see this number climbing, it’s a sign you might need to rethink your strategy and content.
• Open Rates and Click-Through Rates. These numbers reveal how engaged your audience is with your content. Low rates could mean your emails aren’t grabbing attention or aren’t relevant enough.

When it comes to engagement, much like how someone would look for easy options to buy digital assets—like the ability to buy Litecoin with credit cards—your audience looks for straightforward and appealing content in emails. Providing them with such value is essential.

Run A/B Tests on Subject Lines, Content, and Send Times

A/B testing is super useful for figuring out what works best. Try out different elements to see what gets the best results.

• Subject Lines. Test out various headlines to see which ones get more opens. Since the subject line is the first thing people see, it’s important to make it stand out. About 47% of people decide to open an email based on the subject line alone.
• Content. See which types of content get the best reactions. This might be text, images, or links to different offers. Personalization using dynamic content is the top personalization tactic used by email marketing teams. 
• Send Times. Find out when your emails get the most attention. For example, you might discover that emails sent mid-week perform better than those sent on weekends. There’s general stats, but it might not always fit your specific situation.

With Smartlead's AI Auto Adjust A/B Testing feature, you can enhance your campaigns and drive more revenue through booked meetings. Follow these steps to get started:

Once everything is set, launch your campaign. Keep tracking these metrics, keep testing, and keep tweaking your approach to keep your campaigns running smoothly.

Feedback and Adjustments

Feedback from internet service providers (ISPs) helps you understand how your emails are being handled and what issues might be popping up.

• Setting Up DMARC Reports. Configure DMARC reports to get insights into how your emails are passing authentication checks. This will let you see if any emails are failing checks and why.
• Recipient Feedback. Set up a system to gather feedback from your recipients. This can be useful for understanding how they perceive your emails and what you might need to improve.

The more attentive and proactive you are, the better your results will be.
