    Email deliverability – that is, the capacity of your emails to reach the intended inboxes – is absolutely vital in the realm of digital marketing. Many marketers, despite their significance, find themselves struggling with shockingly low deliverability rates, a problem that may significantly affect the outcome of their efforts.

    Now enter Campaign Monitor, a well-known email marketing platform distinguished by strong analytics and easy design tools. Although Campaign Monitor provides a lot of tools to enable businesses and marketers, new studies point to a worrying trend: certain users have clearly declining email deliverability rates. Those who mostly rely on email interactions to reach their audience may find this unanticipated problem frustrating.

    What is email deliverability

    The capacity to effectively reach inboxes of recipients with emails is known as email deliverability. Any email marketing campaign depends on this key statistic since it immediately influences the exposure and interaction of your marketing communications. Your emails most certainly are not being seen, much less acted upon if they are not reaching the inbox.

    Good deliverability means your emails avoid spam filters and other restrictions by more likely reaching the inbox. Higher engagement rates, more possibility for conversion, and closer customer connections follow from this. On the other hand, poor deliverability could damage the reputation of your brand, waste money, and lessen the success of your email marketing initiatives.

    Key Metrics to Measure Deliverability

    • Bounce rates – that is, the proportion of sent emails that might not reach the intended email address. One can categorize bounces as either “soft” (temporary problems, such a full inbox) or “hard,” (permanent issues include a non-existent email address).
    • Open rates – that is, the proportion of emails opened by receivers. This statistic evaluates your email delivery’s first success as well as the appeal of your subject line.
    • Spam Complaints – how often recipients have marked your emails as such? High numbers in here could compromise your sender reputation and general deliverability.

    Factors Influencing Email Deliverability

    • Sender Reputation. Determined by various factors including IP address health, sending frequency, and recipient interaction. A poor reputation can lead to emails being blocked or filtered out.
    • Content Quality. Emails with spam-like material—that is, too many links, poor formatting, or trigger phrases like “free,”—may be flagged by spam filters.
    • List Quality. Sending emails to antiquated or unverified email lists can boost bounce rates and complaints, therefore affecting deliverability.
    • Engagement. Users of your emails are watched by providers. Low engagement can tell providers your material isn’t resonating, thereby influencing future delivery.
    • Authentication Protocols. Using SPF, DKim, and DMARC can help to confirm the legitimacy of your emails and increase delivery.

    Campaign Monitor’s deliverability challenges

    Campaign Monitor deliverability

    Reputable in the email marketing field, Campaign Monitor is praised for its simple layout and thorough statistics. Like every platform, though, it has certain difficulties, especially with relation to email delivery. For marketers depending on Campaign Monitor for their email campaigns, knowledge of these problems is absolutely vital.

    Overview of Reported Deliverability Issues

    • Increased Bounce Rates. Emails being refused by recipient servers have been observed by users suggesting possible issues with list quality or server reputation.
    • Decreased Open Rates. The obvious drop in email recipients opening suggests that either emails are failing to properly engage receivers or are finding themselves in spam folders.
    • High Spam Complaints. Some studies show a rise in the rate at which receivers identify emails as spam, therefore compromising sender reputation greatly.

    Comparison with Industry Standards and Benchmarks

    • Industry Standards. The average email deliverability rate across various industries typically hovers around 85% to 90%. An optimal bounce rate is generally below 2%, and a healthy open rate can vary significantly by industry but is usually expected to be around 20-30%.
    • Campaign Monitor’s Performance. Based on user feedback and several analytic reviews, Campaign Monitor’s performance in these areas has occasionally fallen below these industry standards. Specific metrics such as open and bounce rates have shown variability, sometimes straying from these benchmarks.

    This deviation from expected performance standards highlights the need for ongoing monitoring and adjustment of Campaign Monitor strategies. It also underscores the importance of maintaining best practices in email marketing, such as regular list cleaning, A/B testing of email content, and thorough engagement analysis to ensure that the strategies employed are effectively resonating with target audiences.

    Potential causes for low deliverability

    IP Reputation Issues

    • Shared vs. Dedicated IP Addresses. Using a shared IP address could compromise your email deliverability depending on the actions of other users using the same IP. Should these users conduct in ways that compromise the IP’s reputation—such as spam—your emails may be screened or blocked. In contrast, a dedicated IP address provides control over your sending reputation but requires a larger volume of emails to maintain a good sender score.
    • Impact of Other Users on Shared IPs. The cumulative effect of all users’ activities on a shared IP can lead to its blacklisting, directly impacting deliverability for all users, not just those responsible for poor practices.

    Content-related Issues

    • Trigger Words that Lead to Spam Filters. Certain words and phrases, such as “free,” “guarantee,” or “no risk,” can trigger spam filters, causing emails to be routed to the spam folder rather than the inbox.
    • Poorly Designed Email Templates. Emails that are not optimized for readability or contain excessive graphics might not only trigger spam filters but also affect user engagement negatively, as they may not display correctly across all devices and email clients.

    List Management Practices

    • Email lists of high quality, current are absolutely vital. Lists include purchased, inactive, or old emails could cause high bounce rates and spam complaints, therefore affecting deliverability.


    • Maintaining a good sender reputation and guaranteeing excellent deliverability depend on regular cleaning of email lists to exclude non-engaging subscribers or erroneous email addresses.

    User Engagement Metrics

    Email service companies monitor how users respond to your emails. Low engagement rates—that is, low open and click-through rates—can indicate to providers that receivers show no interest in your material, therefore influencing future deliverability. On the other hand, high participation indicates that receivers think your emails valuable, which might increase your deliverability.

    Strategies for improving deliverability

    👉 Deliverability of your email list directly depends on quality. Eliminating unresponsive or incorrect email addresses from your list can help you to regularly improve your sender reputation and lower bounce rates. Maintaining a high-quality list depends also on using double opt-in techniques whereby members confirm their email addresses. Email lists should not be bought since they could include obsolete or irrelevant contacts and cause significant bounces and spam complaints.

    👉Deliverability depends on keeping up a good IP reputation. If you use shared IP, be sure the email service provider strictly forbids spamming in order to maintain its IP reputation. Using a dedicated IP could help you have better control over your sending reputation for bigger volume senders. Whatever the kind of IP, constant frequency and volume support a good IP reputation. Furthermore, warm up new IPs by progressively raising the email volume sent, hence building a reputation as a reputable sender with ISPs.

    👉 Not only can interesting material capture your readers, but it also promotes good interactions like opens and clicks that might increase your deliverability. Whether through educational materials, entertainment, or advertising fit for their interests, make sure your emails value your recipients. Many people view their emails on mobile devices, hence it’s crucial to make sure your emails are mobile-friendly and to organize them using appealing, simple themes. Follow anti-spam rules also by avoiding misleading subject lines and adding a simple-to-find unsubscribed link. These techniques guarantee that your emails not only follow guidelines avoiding spam filters but also are interesting.
