How to Test Email Placement Before Sending

Testing email placement before launching a campaign ensures your messages land in the right inbox and not in spam or promotions folders. Email providers like Gmail and Outlook use algorithms to filter messages based on sender reputation, content quality, and technical setup. Here's a quick breakdown of the process:

• Why It Matters: Emails in the primary inbox get higher open rates and engagement, directly impacting sales and conversions.
• Tools to Use: Platforms like Warmforge, GlockApps, Mailtrap, and MxToolbox help test placement and identify issues.
• How to Test:
  1. Set up your testing tool and authenticate your domain (SPF, DKIM, DMARC).
  2. Send a test email that mirrors your actual campaign.
  3. Review placement results and fix any flagged issues.
• Fixing Issues: Address problems like poor authentication, spammy content, or low sender reputation. Regularly monitor and retest to maintain deliverability.

Quick Tip: Warmforge offers a free monthly placement test and warm-up slot, making it an affordable option for improving email performance.

Why Email Placement Matters

Reaching the primary inbox is key to boosting open rates, clicks, and conversions. On the flip side, ending up in spam or promotions tabs can tank visibility and hurt long-term engagement.

Email providers in the U.S., like Gmail, Outlook, and Yahoo, rely on advanced algorithms to decide where your emails land. These algorithms take into account factors like sender reputation, authentication, content quality, and how users interact with your messages. For instance, Gmail might divert emails that are frequently marked as spam or deleted without being opened, while Outlook’s Focused Inbox and Yahoo’s strict filters can make life tough for senders with inconsistent practices.

Building and maintaining a strong sender reputation is non-negotiable. Email providers closely monitor metrics like bounce rates, spam complaints, and engagement levels to determine placement. If your emails consistently land in the wrong place, it can create a cycle where poor placement leads to lower engagement, which in turn reduces your chances of future success.

This isn’t just about engagement - it’s about dollars and cents. For businesses, especially in e-commerce, landing in the primary inbox can make or break a campaign. Missed inbox placement often means missed sales opportunities.

Adding to the challenge, filtering algorithms are constantly changing. They’re designed to spot things like overly promotional language, suspicious links, or excessive punctuation. What worked yesterday might not cut it today. And if your email gets relegated to tabs like Gmail’s Promotions, it can significantly reduce engagement for time-sensitive offers.

On top of that, technical setup plays a big role. Emails without proper authentication - like SPF, DKIM, or DMARC records - are often flagged as potentially fraudulent. Setting up these protocols correctly is essential to improve your chances of landing in the primary inbox.

Email Placement Testing Tools

Before launching your email campaign, it's crucial to test where your messages land across major email providers. This section highlights some top tools to help ensure your emails avoid spam filters and reach your audience's inbox.

Warmforge

Warmforge is a deliverability platform that combines placement testing with a suite of optimization tools. Using AI to simulate natural human behavior, it provides accurate insights into how your emails are handled by providers like Gmail and Outlook.

What makes Warmforge stand out is its all-in-one approach. It offers automated email warm-up, real-time monitoring of deliverability, and detailed checks for DNS and MX records. These features make it a go-to choice for businesses aiming to optimize their email campaigns.

Key features include:

• AI-generated email content that mimics natural communication styles.
• Continuous warm-up to maintain and enhance sender reputation.
• Blacklist scanning to identify potential reputation issues early.
• Native integration with Google Workspace and Microsoft 365.
• One free placement test per month for all accounts.
• One free warm-up slot for a Google or Microsoft mailbox to assess its effectiveness.

Warmforge's pricing starts at $9 per mailbox per month (with annual billing), which includes one free placement test and one free warm-up slot every month. It's also part of The Forge Stack, seamlessly integrating with tools like Salesforge for outreach and Primeforge for mailbox management. This makes it especially useful for businesses running large-scale email campaigns.

While Warmforge offers a comprehensive solution, other tools cater to specific needs and preferences.

Other Popular Tools

Here are a few other platforms that specialize in email placement testing, each with unique strengths:

• GlockApps: Known for its detailed spam testing, GlockApps offers features like seed list functionality across multiple providers and in-depth authentication and content reports. However, it doesn't include AI-powered warm-up capabilities. Pricing starts at $49 per month for basic plans.
• Mailtrap: Designed with developers in mind, Mailtrap provides inbox simulation and spam analysis. It's ideal for testing email functionality during development but may not meet the needs of marketers focused on deliverability. Plans begin at around $10 per month.
• MxToolbox: This tool is perfect for technical diagnostics, offering robust DNS and email server analysis, blacklist monitoring, and authentication checks. While it's excellent for IT professionals, its interface and features may not suit marketing teams. Basic monitoring services start at $139 per month.

The best tool for you depends on your goals and expertise. For marketers aiming to improve inbox placement, Warmforge's combination of placement testing and continuous warm-up is highly effective. On the other hand, IT professionals might prefer MxToolbox for its diagnostic capabilities, while developers could benefit from Mailtrap's testing environment.

Given the strict filtering systems of providers like Gmail and Outlook, these tools are essential for navigating the challenges of email deliverability. By leveraging their features, you can ensure your emails reach the right audience and make the impact you intend.

How to Test Email Placement

Testing where your emails land - whether it’s the inbox, spam folder, or promotions tab - can make or break your email marketing efforts. The process is straightforward if you’ve got the right tools and a clear plan. Here’s how to get it done effectively.

Step 1: Set Up Your Testing Tool

Start by creating an account on warmforge.ai. Once you're in, authenticate your domain and connect your mailbox to simulate real-world email delivery.

To make this work, you'll need to add SPF, DKIM, and DMARC records to your DNS settings. These records ensure your emails are verified and help produce accurate results.

If you’re using Google Workspace or Microsoft 365, connecting your mailbox is a breeze. Warmforge uses secure OAuth authentication, meaning it only has permission to send test emails - it doesn’t store your credentials. For other email providers, you can manually configure SMTP settings. A setup wizard will guide you through entering the necessary server details, ports, and authentication options.

Before you send anything, Warmforge runs automatic health checks on your DNS and MX records. This step helps flag any potential deliverability issues upfront. Once everything is good to go, the dashboard will give you a green light, and you’re ready to send your first test email.

Step 2: Send a Test Email

Your test email should look and feel like the real thing. Use subject lines, sender names, and content that closely match your actual campaign. Avoid generic test phrases like “Testing 123” or “Sample Email” - these won’t give you reliable results.

Instead, use subject lines that reflect your campaign's tone and purpose. For the email body, stick to your usual messaging style. If you’re unsure, Warmforge’s AI-powered content suggestions can help you create test emails that align with your brand voice.

Once your email is ready, Warmforge sends it out to major providers like Gmail, Outlook, Yahoo, and Apple Mail. This step simulates how your emails will perform across different inbox environments. The process is quick, and you’ll get a confirmation once the test is done.

Step 3: Review Your Results

After sending, Warmforge generates a detailed report showing where your email landed - inbox, spam, or promotions. The report breaks down placement percentages for each folder, giving you a clear picture of what’s working and what’s not.

It also includes a spam trigger analysis. This feature identifies specific elements in your email - like excessive capitalization, too many exclamation points, or certain keywords - that might cause spam filters to flag your message. On top of that, the report verifies your authentication records and checks your sender reputation against multiple blacklist databases.

You can track your results over time with the dashboard, making it easy to spot trends and measure the impact of any changes you make. With a free monthly placement test, you can stay on top of your email deliverability and ensure your campaigns consistently hit the mark.

How to Fix Deliverability Issues

Once you’ve pinpointed deliverability problems through placement testing, it’s time to address them with precise fixes. Most issues have clear solutions - you just need to know where to start. Below, we’ll dive into common problems and how to resolve them.

Fix Common Problems

One frequent culprit for poor email placement is incorrect authentication. Double-check your domain’s DNS settings to ensure your SPF, DKIM, and DMARC records are set up properly. These records act as your email’s ID, proving to receiving servers that your messages are genuine.

Pay special attention to your DMARC policy, which dictates how receiving servers handle emails that fail authentication. Start with a "p=quarantine" policy to test the waters, then shift to "p=reject" once you’re confident everything is running smoothly.

If your domain or IP address ends up on a blacklist, it can wreak havoc on your deliverability. Emails may bounce or go straight to spam. Regularly check major blacklists like Spamhaus, Barracuda, and SURBL. While most blacklist removals don’t cost anything, you’ll need to fix the underlying issue first. Common causes include compromised accounts, spam complaints, or using purchased email lists.

Content issues are another common problem. Spam filters are quick to flag emails with excessive promotional language, ALL CAPS, or too many exclamation points. Attachments that seem suspicious can also hurt your chances. Avoid words like “FREE,” “URGENT,” or “ACT NOW,” as these are red flags. Instead, opt for natural, conversational language that gets your message across without setting off alarms.

Improve Content and Sender Reputation

Your technical setup is only part of the equation - your content and sender reputation also play a big role in deliverability.

Your sender reputation is like a credit score for your email domain. A strong reputation takes time to build but is crucial for landing in inboxes. Keep bounce rates low - anything above 2% is concerning, and rates over 5% are a red flag.

For new domains or email addresses, email warm-up is essential. Cold outreach from a brand-new account often ends up in spam. Tools like Warmforge’s automated warm-up service can help. These tools gradually increase your sending volume while mimicking natural email exchanges, helping you establish trust with email providers. This process typically takes 2-4 weeks.

Optimizing your content goes beyond avoiding spam trigger words. The goal is to create emails that people actually want to read and engage with. High open rates, click-through rates, and positive responses signal to email providers that your content is worth delivering. Personalize your emails thoughtfully - subject lines and body text should feel relevant but not overly intrusive.

Balance your text-to-image ratio carefully. While images can make your emails visually appealing, messages dominated by images with little text often get flagged as spam. Aim for a 60/40 or 70/30 text-to-image ratio, and always include alt text for images. This not only improves accessibility but also gives spam filters more context about your email.

Monitor and Retest Regularly

Even after fixing issues, regular monitoring is key to maintaining good deliverability. Email providers frequently update their algorithms, and your sender reputation can shift based on recent activity. Set up a monthly testing schedule to stay ahead of potential problems.

Seasonal changes can also impact deliverability. During high-volume periods like Black Friday, the holidays, or back-to-school sales, email providers often tighten their filters. During these times, test your placement more frequently to ensure your emails still make it to inboxes.

Warmforge offers a free monthly placement test to help you track progress. Document your results, including dates, placement percentages, and any changes to your setup. This historical data helps you spot trends and evaluate the success of your adjustments.

For major campaigns, like a product launch or a big promotion, campaign-specific testing is a smart move. If you’re emailing a segment you haven’t contacted in a while, run a placement test beforehand. Regular monthly checks can reveal gradual shifts, but sudden declines require immediate attention. Often, the fix is simple - cleaning your email list or tweaking your sending schedule can make a big difference.

Conclusion

Getting your emails into the inbox is critical for successful outreach. Without proper placement testing, your messages risk landing in the spam folder, which can derail your entire campaign. Whether you're focused on sales, marketing, or customer communications, poor deliverability often translates to lost revenue and missed opportunities.

That’s where a tool like Warmforge comes in. It simplifies the process with features like automated placement testing, an AI-powered warm-up service, and regular health checks. Together, these tools help safeguard your sender reputation and keep your emails consistently landing where they belong - in the inbox.

By testing your emails before hitting "send", you can catch and resolve deliverability issues early, avoiding the frustration of campaigns that fall flat. It’s all about taking control of your email performance before problems arise.

What common mistakes cause emails to end up in spam or promotions folders?

Emails can end up in spam or promotions folders for a variety of reasons, many of which are completely avoidable. Common culprits include using spam-trigger words in subject lines or email content, relying on unverified or purchased email lists, or neglecting to authenticate your sender domain with protocols like SPF, DKIM, and DMARC. Another red flag for spam filters? Overloading your emails with too many images or links.

Other issues that can hurt your email placement include inconsistent sending patterns, sending large volumes of emails without a proper warm-up period, and poor list segmentation. These mistakes can lead to lower engagement rates, which, in turn, signal to email providers that your messages might not be relevant.

To boost your email deliverability, focus on building a clean, verified email list, crafting personalized content, and maintaining consistent sender behavior. Tools like Warmforge can be a game-changer by offering placement tests and deliverability monitoring to help you fine-tune your email strategy.

What is email warm-up, and why is it crucial for new domains?

Email warm-up involves slowly ramping up the number of emails you send to establish a trustworthy reputation with email providers. This process helps ensure your messages bypass spam filters and reach your recipients' inboxes. It's especially crucial for new domains, as it builds trust, enhances deliverability, and reduces the chances of your emails being marked as spam.

Tools like Warmforge can simplify this process by simulating natural email activity. They automate the warm-up, safeguard your sender reputation, and increase the effectiveness of your outreach campaigns.
