Email Verification Strategies for B2B SaaS Sales Teams

In the bustling world of B2B SaaS sales, the email is a goldmine if used effectively. It's a direct channel towards your prospective leads, and maintaining its efficiency is paramount. However, amidst a sea of spam, bot emails, and outdated contacts, how do you ensure that the email addresses you collect and use are valid?

That's where email verification comes into play. This blog post delves into the strategies and tools B2B SaaS sales teams can employ to maintain a robust, accurate, and effective email list, enhancing both engagement and conversion rates.

The Importance of Email Verification

First, let's clarify why verifying emails is critical:

  1. Improve Deliverability Rates: Sending emails to invalid addresses can significantly impact your sender reputation and decrease your deliverability rates.
  2. Increase Engagement: Accurate email lists mean your emails reach genuine prospects, leading to higher open rates, click-through rates, and engagement.
  3. Cost Efficiency: Email marketing platforms often charge based on the number of emails sent. Invalid emails waste your marketing dollars on undeliverable content.
  4. Reduce Bounce Rates: High bounce rates can trigger email service providers (ESPs) to flag your account as a spammer, decreasing your email deliverability and harming your campaigns.

Effective Email Verification Strategies

1. Double Opt-In Method

The double opt-in method ensures that a new subscriber manually confirms their subscription to your email list. When a user signs up, they receive a confirmation email asking them to verify their email address. Only those who click on the verification link are added to your list.

Advantages:

  • Ensures the email address is valid.
  • Confirms genuine interest from the subscriber.
  • Reduces the risk of spam complaints.

Example Workflow:

  1. User signs up on your website.
  2. An automatic email is sent to the user for confirmation.
  3. User clicks on the confirmation link.
  4. Email address is added to the verified list.

2. Regular List Cleansing

Periodic cleansing of your email list helps in identifying and removing invalid or outdated email addresses. This ensures that your list remains current and effective.

Actions to Take:

  • Remove emails with hard bounces.
  • Segment out inactive subscribers and run re-engagement campaigns.
  • Use email verification tools to scan and validate your list periodically.

Tools for List Cleansing:

3. Validation at Point of Capture

Implement email verification at the point where users input their email addresses, such as signup forms or landing pages. This strategy involves using an API that instantly checks the validity of the email address entered.

Advantages:

  • Prevents invalid email addresses from entering your list.
  • Reduces manual cleansing efforts later.
  • Enhances user experience by prompting corrections in real-time.

Popular APIs:

4. SMTP Verification

SMTP verification involves checking the email address at the server level without sending an actual email. By pinging the SMTP server, you can confirm if the email address exists and is valid.

Procedure:

  • Connect to the SMTP server of the recipient's domain.
  • Simulate sending an email to check if the email address is valid.
  • Disconnect without sending an actual message.

Caveat:

  • Some servers are configured to accept all emails, making this method not 100% foolproof.

5. Check Email Syntax and Domain

A basic but effective strategy is to verify the syntax and domain of the incoming email addresses. Ensure the email follows standard email formatting rules and that the domain exists and has a working mail server.

Syntax Rules:

  • Contains an "@" symbol.
  • Valid domain name format (e.g., example.com).
  • No special characters outside the allowed set (ex: ! # $ % & ' * + - / = ? ^ _ { | } ~`).

Domain Verification:

  • Use DNS lookup to ensure the domain exists.
  • Check for an MX (Mail Exchange) record that points to a mail server.

Metrics to Monitor

To ensure your email verification strategies are effective, keep an eye on these key metrics:

  1. Bounce Rate: A high rate indicates many emails are undeliverable. Aim to keep this below 2%.

  2. Open Rate: A healthy open rate shows that your emails are reaching valid, interested recipients.

  3. Click-Through Rate (CTR): A higher CTR suggests that your emails resonate with the audience and prompt actions.

  4. Conversion Rate: Measures the end goal of your campaigns, reflecting the effectiveness of your sales funnel.

  5. List Growth Rate: Track how quickly your verified list is growing while ensuring quality is maintained.

  6. Spam Complaints: Monitor the percentage of recipients marking your emails as spam. High numbers indicate issues with your content or list hygiene.

Best Practices for Maintaining a Clean Email List

Even with robust verification strategies, ongoing maintenance is crucial. Here are some best practices:

1. Regularly Update and Cleanse Lists

Frequent cleansing (every 3-6 months) helps to remove any invalid addresses that may have slipped through.

2. Segment Your Audience

Segment your email lists based on engagement levels and other criteria to target active and interested recipients more effectively.

3. Authenticate Your Sending Domain

Implement DKIM, SPF, and DMARC policies to authenticate your sending domain, enhancing your email deliverability and protection against spoofing.

4. Monitor Deliverability Metrics

Keep an eye on your domain’s deliverability metrics regularly, and take proactive measures when you notice anomalies.

5. Engage with Your Subscribers

Send regular, value-driven emails to maintain engagement and reduce the risk of inactive subscribers.

6. Prompt Error Corrections

During the signup process, prompt users to correct any mistakes in their email addresses immediately with real-time validation tools.

7. Avoid Purchased Lists

Purchased lists often contain outdated or invalid email addresses and can seriously harm your deliverability rates and reputation.

8. Run Re-Engagement Campaigns

For inactive subscribers, run re-engagement campaigns to either win them back or remove them from your lists to ensure high engagement rates.
