An aged domain is more likely to have a good reputation, which increases the chances of placing the email in the inbox.

To maintain a good IP reputation, sending emails to a targeted and engaged list of recipients is important. Sending irrelevant emails to many recipients can result in high complaints, unsubscribes and negatively impact your IP reputation.

SPF, DKIM, and DMARC Protocols

These are authentication protocols that help to ensure that your emails are coming from a legitimate source. Be sure to set these up for your domain.

SPF, DKIM, and DMARC are three email authentication methods that ensure that an email comes from a legitimate source.

SPF (Sender Policy Framework) is a method that allows the owner of a domain to specify which mail servers are authorized to send emails on their behalf. The receiving server verifies the email’s sender by checking the domain’s SPF record.

DKIM (DomainKeys Identified Mail) is a method that allows the owner of a domain to add a digital signature to their emails. DKIM verifies that an authorized server sent the email.

DMARC (Domain-based Message Authentication, Reporting & Conformance) is a method that allows the owner of a domain to publish a policy that tells receiving mail servers what to do with emails that fail SPF or DKIM authentication. DMARC allows domain owners to prevent phishing and email fraud by rejecting or quarantining emails that fail authentication.

Implementing these methods is important to protect your domain from malicious actors who can misuse your domain name to send spam emails, phishing emails, and fraudulent emails. includes an email server and the respective SPF, DKIM, and DMARC entries with all plans.

Content Repetition

Email service providers punish repetitive content. Avoid content repetition to prevent deletion or spam.

Spintax can create variations of any part of your email, including the subject line, body text, and even the signature. Using spintax, you can ensure that each email you send is unique. supports spintax and nested spintax to avoid content repetition. Learn more about how to use spintax.

Email Personalization

Some antispam systems use algorithms to analyze the content of an email and determine if it is personalized or appears to be mass-produced. Personalized emails are generally seen as less likely to be spam, while emails that appear to be mass-produced and contain generic content are more likely to be flagged as spam.

It’s important to note that the level of personalization can affect the overall deliverability of your emails, and using personalization in a spammy or manipulative manner can harm your deliverability and reputation.

Email Sending Volume

Email sending volume is an important aspect of cold email outreach campaigns because it can affect your emails’ deliverability and response rate. Low response rates and marking as spam can occur from sending too many or too few emails.

It’s important to strike the right balance when it comes to email sending volume. One way to do this is to start with a small volume of emails and gradually increase it over time. An “email volume ramp-up” approach allows you to test your emails’ response rate and deliverability before sending many of them.

Additionally, if you are targeting a small and specific audience, you may only need to send a few emails to generate a good response rate.

Another important aspect to consider is the email frequency schedule. To avoid marking your emails as spam, it is important not to send too many emails quickly, as it can overwhelm the recipient’s mailbox. Instead, it’s better to space out your emails and send them consistently over a longer period. includes email frequency settings ranging from one email every 45 seconds to one email every 10 minutes. The slower you send, the more natural your email frequency will be perceived, increasing the chance of primary inbox placement.

Email Template Length

The length of an email template is an important factor to consider when conducting cold email outreach campaigns. Writing a concise email can help improve your response rate, while a lengthy template can result in recipients ignoring your emails.

The main reason for the importance of the length of an email is that people are more likely to read and respond to shorter emails. People quickly scan the subject and first lines to decide if an email is worth reading.

Another reason is that a shorter email template is more likely to be opened and read. Keep email templates short for better readability and response rates.
