Why Do You Need Email Deliverability Consultant?

An email deliverability audit is essential. It involves setting email goals, collecting information, running tests, interpreting results, and developing an improvement strategy. The collaboration should go beyond the audit to ensure continuous improvement.

However, there are things even the best consultant can't influence, such as making ISPs accept your mail or forcing third parties to see you as a reputable sender. Think of a consultant as a mechanic who can fix your car, but you still need to steer it.

How Does Email Deliverability Work?

Okay, let's break down how email deliverability works in simple terms!

When you send an email, it's like sending a letter through the Internet. The goal is to make sure your email reaches the recipient's inbox and doesn't get lost in the virtual world or end up in the spam folder.

Here's how it works:

  1. Sending the Email: You hit the "send" button, and your email travels through the internet to reach the recipient.
  2. Internet Journey: The email goes through various checkpoints on the internet. These checkpoints are like virtual post offices that decide whether your email is safe or not.
  3. Spam Filters: Just like how real mail might be checked for suspicious things, emails also face spam filters. These filters look for signs that an email might be unwanted or harmful.
  4. Reaching the Inbox: If your email passes all the checks and looks trustworthy, it lands in the recipient's inbox. That's the goal – to ensure your message gets where it's supposed to go!
  5. Avoiding the Spam Folder: If your email raises too many red flags, it might end up in the spam folder instead of the inbox. That's not ideal because people often don't check their spam folders regularly.
This is how email deliverability works

What Are Email Deliverability Issues?

Addressing specific email deliverability issues requires a comprehensive strategy. It includes monitoring, authentication, content optimization, and adherence to industry best practices. Some email deliverability issues might land your emails in recipients' spam traps or even bring bad news for you.

01. Spam Filters

Emails might get flagged as spam and end up in recipients' spam or junk folders. Filters are triggered by certain content, formatting, or sender behavior.

02. Blacklists

Inclusion of sender's IP or domain in email blacklists due to previous spam-like activities. Being on a blacklist can lead to widespread email deliverability issues.

03. Poor Sender Reputation

Email engagement, spam reports, and other factors determine a sender's reputation. Low sender reputation can result in emails being marked as spam or blocked.

04. Authentication Failures

Issues with SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), or DMARC (Domain-based Message Authentication, Reporting, and Conformance) authentication. Failing to authenticate properly can lead to email deliverability problems.

05. Bounces And Unsubscribes

High bounce rates (undelivered emails) and frequent unsubscribes negatively impact the sender's reputation. Maintaining a clean and updated email list is crucial.

06. Low Engagement Rates

Emails not generating sufficient opens, clicks, or other positive interactions. Low engagement signals to email providers that recipients are disinterested.

07. Incorrect Email Configuration

Misconfigurations in SMTP (Simple Mail Transfer Protocol) and authentication protocols. Incorrect setups can cause emails to be misrouted or marked as suspicious.

08. Phishing Concerns

Emails are perceived as phishing attempts due to certain content or sender behavior. Phishing concerns can lead to ISPs blocking or filtering out emails.

09. Inconsistent Sending Practices

Rapid changes in email sending volumes or patterns. Abrupt changes can trigger spam filters and affect deliverability.

10. IP Warming Issues

When starting to use a new IP address, gradually increasing email sending volume is crucial. Failure to warm up the IP properly can result in deliverability challenges.

11. Content Issues

Using overly promotional or suspicious language in emails. Content that resembles common spam practices can trigger filters.

12. Failure To Monitor And Adapt

Not regularly monitoring email deliverability metrics. Failing to adapt strategies based on changes in the email landscape or ISP policies.

13. Lack Of Email List Hygiene

Regularly cleaning and updating email lists is also very important. Inactive or incorrect email addresses can contribute to deliverability issues.

14. ISP-Specific Rules And Policies

Different ISPs may have unique rules and policies for email deliverability. Failure to adhere to these specific requirements can impact delivery rates.

15. Non-Compliance With Regulations

Not adhering to email marketing regulations such as the CAN-SPAM Act or GDPR. Non-compliance can lead to legal issues and affect the sender's reputation.
