ConvertKit deliverability: Why it's low & not working?

Talk with a deliverability expert!

No need to flee, it’s totally free


    Have you ever wondered why some of your painstakingly created emails wind up in the spam bin, or worse, never get even to your intended recipient? ConvertKit has become a preferred tool for artists and marketers trying to personally interact with their audience in the cutthroat realm of email marketing. But a concerning pattern has been observed: many customers claim shockingly poor email delivery rates.

    What does this mean for your marketing efforts? Consider this: industry benchmarks show that a good email deliverability rate should hover around 95%, yet a significant number of ConvertKit users find themselves grappling with figures much lower than this. Lets figure out.

    What is email deliverability?

    In email marketing, email deliverability is a key indicator of how likely your emails will find their way to the recipient’s inbox instead of being filtered off or rejected by mail servers. Its significance is impossible to overestimate; after all, if an email never gets seen, even the most interesting one is useless.

    Several important elements determine whether your email lands in the abyss or reaches the inbox. First, there’s the sender’s reputation – your history of delivering emails users interact with favorably. Internet service providers (ISPs) monitor this closely; a bad reputation can destroy your communications.

    Also very important is the substance of your emails. Sophisticated algorithms meant to guard consumers from unwelcome mail routinely block emails that seem spammy, whether from their text or too aggressive subject lines.

    Participation from recipients affects deliverability even more. ISPs track how users interact with your emails – if they often open, respond to, or designate your emails as critical, your deliverability increases. On the other hand, your sender reputation may suffer if your emails are routinely deleted without being viewed, worse still, labeled as spam.

    Finally, one cannot overlook technological settings. Correct setup of your email infrastructure – that is, setting up appropriate SPF, DKim, and DMARC records – helps confirm your identity as a sender and guarantees ISPs are more likely to believe your emails.

    Analyzing ConvertKit's deliverability issues

    ConvertKit deliverability

    ConvertKit, known for its user-friendly interface and robust features aimed at bloggers and content creators, has faced challenges that might surprise many of its users: lower-than-expected email deliverability rates. Various reports and user feedback have highlighted this issue, raising concerns among its loyal user base.

    A deeper look into the experiences of several ConvertKit users reveals a pattern of deliverability challenges. For instance, some bloggers have noted that their audience engagement dropped significantly after switching to ConvertKit, despite maintaining consistent content quality and engagement strategies. Others have shared screenshots and data comparisons showing a noticeable decrease in open rates and an increase in bounce rates after their emails began bypassing the inbox for the spam folder.

    When these deliverability rates are stacked against industry standards, the contrast becomes more apparent. The email marketing industry typically expects deliverability rates in the range of 95% or higher, as a sign of healthy email practices and robust infrastructure. However, anecdotal evidence suggests that ConvertKit users frequently experience rates considerably lower than this benchmark. This discrepancy points to potential underlying issues within ConvertKit’s infrastructure or its handling of key factors such as sender reputation management and technical email settings.

    Such comparisons not only highlight the struggles ConvertKit users face but also underscore the importance of continuous monitoring and adjustment of email marketing practices to maintain high deliverability.

    Technical сhallenges

    Navigating through Salesforce to check and enhance email deliverability involves a series of steps tailored to different environments within the platform. Here’s how you can ensure your emails are making their mark:

    IP Reputation and Its Management

    Should even a few users adopt bad sending habits, the IP addresses from which ConvertKit emails could become contaminated. For all users sharing those IPs, this can significantly impact the deliverability since ISPs may blacklist or deprioritize these addresses depending on their overall reputation.

    SPF and DKIM Settings

    These are vital email authentication techniques—Sender Policy Framework and DomainKeys Identified Mail, respectively—that enable one to confirm that the emails delivered are indeed from the specified domains and not spoofed. SPF and DKim Settings Bad setups of these settings could cause the recipient’s email server to reject emails or mark them as spam. ConvertKit offers set instructions, however improper user application can cause deliverability problems.

    Frequency and Volume of Emails

    Deliverability can be affected by email frequency and volume as well as by their pace of arrival. Particularly if receiver involvement is modest, high numbers or frequent transmissions can set spam filters off. Maintaining subscriber interest depends on juggling the frequency and number of emails to prevent being labeled as spam.

    Handling Bounces and Spam Complaints

    ConvertKit features systems to monitor and handle email bounces and spam concerns. The technology automatically deletes email addresses that regularly bounce, therefore lowering the possibility of future email blockings. ConvertKit also works in feedback loops with big ISPs, which lets them get alerts when a recipient tags an email as spam, therefore enabling them to react and modify their plans to increase deliverability.

    User practices contributing to low deliverability

    Although email deliverability is mostly dependent on technological factors, user behavior greatly affects how successfully emails find their intended recipients. ConvertKit users often make these frequent errors that could compromise email deliverability:

    Poor List Hygiene Practices

    Maintaining a clean email list is absolutely vital, yet sometimes disregarded. Those that neglect to routinely clean their lists could find themselves emailing inactive or invalid addresses, hence raising bounce rates and compromising sender reputation. Deliverability can be greatly enhanced by routinely deleting unengaged members, erroneous email addresses, and opt-out users.

    High Frequency of Emails

    Sending too many emails might cause user fatigue, in which case receivers feel overwhelmed by the volume of communications they receive. Higher unsubscribed rates and more spam complaints – both of which compromise deliverability – usually follow from this. Maintaining subscribers’ interest without overloading them depends on striking the proper mix in email frequency.

    Ineffective Segmentation and Personalization

    Generic, one-size-fits-all emails are less likely to interact with recipients depending on ineffective segmentation and personalizing. ConvertKit offers strong options for segmentation and personalizing, however poor use of these capabilities may result in reduced open and involvement rates. Customizing emails to fit the particular requirements and interests of various subscriber groups can greatly increase involvement and, hence, deliverability.

    Evaluating the accuracy of ConvertKit's metrics

    In email marketing, the success of campaigns is often measured using key metrics such as open rates, click-through rates, and bounce rates. These metrics provide insights into how effectively an email reaches and engages its audience. However, the accuracy of these metrics, particularly within platforms like ConvertKit, can be subject to various influencing factors.

    Reliability of ConvertKit's Metrics

    ConvertKit, like many email service providers, measures open rates by embedding a tiny, invisible image in each email, which, when loaded by the recipient’s email client, signals an ‘open’. However, this method faces challenges:

    • Impact of Email Blockers and Privacy Settings. Modern email clients and dedicated email blockers can prevent the loading of tracking pixels, leading to underreported open rates. Additionally, privacy-focused updates like those in Apple’s Mail Privacy Protection allow users to block this tracking, causing further discrepancies in open rate data.
    • Potential Discrepancies in Reporting. There might be discrepancies due to technical issues like delays in data processing or errors in tracking pixel implementation. Such discrepancies can skew metrics, providing either an overly optimistic or pessimistic view of campaign performance.
    • Comparative Analysis with Industry Benchmarks. When ConvertKit’s reported metrics are compared with industry benchmarks, deviations can be noticed. These deviations might arise from the unique demographic or behavior of ConvertKit’s user base, or from systemic measurement errors within ConvertKit’s tracking methods.

    Challenges in Data Collection and Reporting

    • ConvertKit and other platforms often face challenges in accurately collecting and reporting data due to the dynamic nature of email technologies and user behaviors. Changes in technology, updates in privacy laws, and varying email client behaviors can all impact how data is collected and interpreted.
    • Misconfigurations in campaign settings or issues in the segmentation of audiences can also lead to inaccuracies in reported metrics, affecting decisions based on these numbers.

    ConvertKit’s Infrastructure and Policies

    ConvertKit’s capabilities and reputation as an email marketing tool are not only shaped by its features but also by its underlying infrastructure and the policies it enforces to maintain quality and compliance among its users.

    Email Sending Infrastructure

    ConvertKit utilizes a robust infrastructure designed to handle the large volume and frequency of emails that its users send. This infrastructure includes:

    • Multiple Dedicated IP Addresses. ConvertKit manages a range of IP addresses to distribute the sending load. This segmentation helps in isolating reputational issues and ensures that the behavior of one set of users doesn’t impact the deliverability of others.
    • Integration with Major ISPs. ConvertKit works closely with major Internet Service Providers (ISPs) to ensure emails are optimized for delivery. This includes regular updates to align with changing ISP requirements and using feedback loops to respond to issues like spam complaints.
    • Advanced Email Delivery Systems. The platform employs sophisticated algorithms to optimize send times and to pace the delivery of emails. This helps in avoiding sudden surges that might trigger spam filters and ensures a steady flow of communications.

    Improving deliverability with ConvertKit

    Regular List Cleaning and Maintenance

    Maintaining a good sender reputation depends on keeping an email list free from mistakes. Users of ConvertKit should routinely remove inactive subscribers, fix or delete undeliverable email addresses, and segment lists depending on subscriber involvement. This increases general deliverability while lowering bounce rates.

    Strategies for Improving Recipient Engagement

    ISPs evaluate this important statistic closely while deciding whether to categorize emails as spam. ConversionKit users can increase involvement by:

    • Providing focused material catered to the requirements and interests of the audience.
    • Using the recipient’s name or customizing materials depending on past interactions helps to personalize emails to boost relevancy.
    • Optimizing send timings to when subscribers are most likely to read their emails, which ConvertKit may help ascertain by means of statistics.

    Tips on Optimizing Email Content to Avoid Spam Filters

    • Steer clear of employing too aggressive words connected with spam, such “buy now,” “free,” “guarantee,” etc.
    • Emails heavy on images may be identified by spam filters so make sure they are well-designed, balancing text and images suitably.
    • Not simply a great practice but often a legal obligation in many countries is a clear, simple-to-use unsubscribed link.
