What leads to poor email deliverability?
Let’s explore some key aspects related to email deliverability:
1. Sender Reputation: ISPs assess the reputation of the sender based on various factors, such as the sender’s IP address, domain, sending practices, and recipient engagement metrics. A positive sender reputation increases the likelihood of emails being delivered to the inbox, while a poor reputation can lead to emails being sent to the spam folder or blocked altogether.
Long story short, based on your consistent practices, like open rates received, responses received, marked as spam, click-through rates, the volume of emails sent regularly, your content, and probably a hundred other metrics are tracked to build a reputation of your email. You can consistently track your domain reputation from Google’s Postmaster Tools.
If you have a new domain and are considering starting cold emailing, I would strongly suggest warm-up your emails at least 14-25 days in advance, and monitor the warm-up health consistently. If you skip this, be ready to see your emails going to spam and promotions, while your prospects might not see it. There are tons of tools like Instantly, and Lemwarm which can help you with the warmup.
2. Email Content: The content of an email can impact deliverability. Emails with suspicious or spam-like content, excessive use of promotional language, or misleading subject lines are more likely to be filtered as spam. Crafting well-designed and relevant emails that provide value to recipients helps improve deliverability.
I personally ensure that my email content follows these best practices:
- No spam & promotional words.
- No HTML content.
- Low image-to-text ratio (Use fewer images)
- Not too many unnecessary links & long links (stick to a maximum of 1-2 links as CTA)
- No colorful text or many CAPITALIZED WORDS, avoid changing different fonts and sizes.
- Avoid large & shady attachments.
- Use Spintax (The email providers track if you are sending the same content to everyone and score you accordingly, so use [Hi, Hey, Hello] or [Best, Kind Regards, Thanks, Regards] or other areas interchangeably, along with a greater level of personalization.)
- Provide an option to unsubscribe or opt-out, either by link or by replying to you.
- Avoid too many special characters.
- Avoid unnecessary emojis until it’s a B2C email, and avoid grammatical mistakes.
3. Authentication Protocols: Implementing authentication protocols, such as SPF, DKIM, and DMARC, helps verify the authenticity of emails and protects against spoofing and phishing attempts. These protocols add an extra layer of trust for ISPs, increasing the chances of emails reaching the inbox.
Having a misconfigured SPF, DKIM, or DMARC would lead to email providers coming down heavily on your domain. Set it well rightly. You could verify the configuration from the MxToolbox.
Without the right configuration, there is a certain level of suspicion about the authenticity of your emails, which could hamper your deliverability largely.
4. Recipient Engagement: ISPs consider recipient engagement metrics, such as open rates, click-through rates, and replies, to determine the quality and relevance of emails. Higher engagement indicates that recipients find the emails valuable, which can positively impact deliverability.
This is where email warmup may help you, to get started. It artificially builds a good reputation for you, by emulating real human-like conversation, engagements, replies, Click through rates (CTR), and so on. This also includes a daily pattern in which you are sending emails.
For example, say, you sent 20 emails today, 25 tomorrow, and 24 days after, and if you send 300 the next day, it is seen as a spike and unusual behavior. Break down your campaign and build consistency across your email-sending patterns. This is critical for your deliverability, apart from having good open rates and reply rates which can be due to compelling subject/content and actionable CTA.
5. Bounce Rates: Bounces occur when an email cannot be delivered to the recipient’s mailbox. High bounce rates can negatively affect deliverability as ISPs interpret them as a sign of poor list quality or sending practices. Monitoring and managing bounce rates is essential to maintaining good deliverability.
You need to consistently improvise your prospect list, keep a check on the verification of email lists, consistently remove unsubscribers, remove inactive users, and maintain cleanliness.
If the email does not exist, you could be penalized for the hard bounce. If the percentage of hard bounces is high, your ISPs could penalize it and your deliverability may be negatively impacted.
Similarly, A soft bounce in the email refers to a temporary failure in delivering an email to the recipient’s mailbox, which could happen if the end user’s mailboxes are filled, or any other reasons leading to temporary failures.
6. Feedback Loops and Complaints: ISPs provide feedback loops that allow recipients to report unwanted or spammy emails. A high number of complaints can harm the sender’s reputation and deliverability. Handling complaints promptly and adhering to unsubscribe requests are important for maintaining a positive sender reputation.
Additionally, keep a tap on blacklists and spam lists and make a point to not feature in them.
I recommend an additional hack, use alternate domains, if you are creating large-scale outbound campaigns, for example, zintlr.com could have zintlr.net or zintlr.in and so on.
