    When it comes to crafting written content, two critical elements come into play: “perplexity,” which measures intricacy, and “burstiness,” which evaluates sentence diversity. For a captivating piece, human writers masterfully weave both into their work, alternating between short and long sentences. Conversely, AI-generated text often lacks such natural variety, sticking to a uniform sentence length. To create compelling content with desirable perplexity and burstiness, one must bear this in mind.

    In the realm of content creation, artificial intelligence tends to employ phrasing that differs from human choices. By embracing unusual terminology, the originality of the piece is elevated, capturing readers’ attention effectively.

    Below, we delve into the crucial topic of enhancing the deliverability of email newsletters and how warming up a domain plays a pivotal role in this regard.

    To secure the success of an email campaign, getting the message delivered, opened, and read is paramount. However, deliverability depends on numerous factors. In this discussion, we explore the process of warming up a domain before initiating the mailing process.

    To prevent emails from getting lost in spam folders, domain warming is essential. All email service providers exercise caution when it comes to mailings from new domains. Such domains are viewed as potential spam sources, and to counter this perception, the sender’s email address undergoes a warming process. This entails gradually increasing the number of emails sent from the domain, thus building a positive reputation over time.

    Achieving a proper domain warm-up is crucial, as it instills trust among recipients.

    Domain warming can be conducted either manually or through dedicated warm-up services like Warmy.

    Manual domain warm-up

    Opting for manual domain warm-up can be a time-consuming and gradual process. It demands constant attention and considerable effort.

    Based on our experience, we recommend a warming period of at least 1.5-2 months for a new domain. The process must be gradual; sending 200 emails a day right from the start presents a 99.9% chance of ending up in spam folders, thus ruining the domain’s reputation.

    The first step is to assemble a database of genuine and functional email addresses, to which emails from the new domain will be sent.

    Each email needs to be accessed and interacted with, whether by opening and responding or marking as important, even if it initially lands in the spam folder. Building trust and proving that the sender is genuine, delivering valuable content rather than spam, is crucial.

    The process entails engaging with real individuals possessing unique addresses and functional mailboxes. Having assistance from such individuals who use different email providers can be immensely beneficial.

    The aim is to demonstrate one’s authenticity and the importance of their emails to the recipients, fostering a positive reputation.


    Day 1-5

    Initiate with no more than 5 emails to new recipients.

    Personalize each email; avoid using spam words, images, or links.

    Ensure responses to these initial emails.

    Day 6-14

    Gradually increase the number of emails to 10-15 daily, following the same conditions.

    Day 15-25

    Scale up to 50 emails daily, continuing to increase the volume gradually. Respond to the majority of emails from the new email box.

    Day 25-45

    Continue gradually increasing the number of sent emails; by around day 45, the domain should be well-warmed. Sustain interactions with contacts who have responded during this period.

    Now, real email campaigns can be launched, but caution must be exercised. Avoid jumping from 100 emails a day to 1000; instead, continue sending emails incrementally, monitoring open rates and other indicators. Correct any mistakes promptly, as the domain’s reputation can be damaged quickly and irreversibly.

    By the second month, the daily email count will likely be between 50-100.

    As evident, the manual domain warm-up process demands significant effort.

    In our view, dedicating energy and, more importantly, time to domain warm-up might not be worthwhile, considering the availability of automated warm-up services.
