Frequently asked questions

Your questions answered.
What are spam keywords?
Spam keywords are words or phrases that email filters often associate with spam or promotional content. Common examples include "free," "guarantee," "act now," or "limited time offer." These trigger words can cause emails to land in the recipient’s spam folder, reducing the likelihood that your message will be seen.
How do spam keywords affect email deliverability?
Spam keywords can negatively impact email deliverability by increasing the chances that your email gets flagged by spam filters. Deliverability refers to whether your email reaches the recipient’s inbox, so avoiding spammy words helps ensure your message isn’t redirected to the spam or junk folder.
Does avoiding spam keywords guarantee my email will land in the inbox?
No, avoiding spam keywords is just one factor. Other factors that affect deliverability include sender reputation, email list quality, the inclusion of suspicious links or attachments, and whether recipients engage with your email (open, click, etc.).
What is email deliverability and why is it important?
Email deliverability refers to the ability of your emails to successfully reach your recipients’ inboxes, rather than being filtered into spam or rejected. High deliverability is critical because it ensures your message is actually seen and acted upon.
Why do spam filters exist and how do they work?
Spam filters exist to protect users from unwanted or malicious emails. They use algorithms to analyze emails based on certain criteria, such as spammy language, attachments, sender IP reputation, and user engagement patterns. If an email matches known spam characteristics, it may be sent to the spam folder.
Does the frequency of my emails affect deliverability?
Yes, sending too many emails in a short period can negatively impact deliverability. Spam filters may flag your domain or IP as spam if you send a high volume of emails without proper engagement. It’s essential to balance frequency and content quality to maintain a good sender reputation.
What is sender reputation, and how does it affect my cold emails?
Sender reputation is a score that ISPs (Internet Service Providers) assign to your domain or IP address based on the quality of your email-sending practices. A poor sender reputation (due to sending spammy emails or having high bounce rates) can result in your emails being blocked or filtered to spam. To improve sender reputation, use proper list hygiene and avoid spammy practices.
Can I use certain spam keywords if they are relevant to my email?
Yes, but use them cautiously and in moderation. If you need to use certain terms (e.g., "free trial" for a genuine offer), ensure the rest of your email is well-written and avoids other spam triggers. Personalization and context can help improve deliverability even when using riskier words.
How does personalization impact email deliverability?
Personalization improves deliverability because it shows that your email is tailored to the recipient rather than being part of a mass promotional campaign. Using the recipient’s name, company, or specific details increases the chance that the email will be opened and acted upon, which signals to email providers that your emails are relevant and trustworthy.
How can I test my emails for spam triggers before sending?
You can use email testing tools that scan your content for spam keywords, analyze the technical setup (like domain verification), and provide feedback on how likely your email is to land in the inbox. Your tool, which focuses on identifying spam keywords, is a great start in this process.
What role does HTML formatting play in email deliverability?
Using poorly coded HTML or overly complex formatting can trigger spam filters. Avoid overly complex designs, minimize the use of images, and ensure that your emails are mobile-friendly. Always test your HTML emails across different email clients before sending.
