Ensuring email delivery and avoiding spam filters

Over-enthusiastic spam filters unfortunately get it wrong sometimes. Luckily, Bookem knows how to ensure successful email delivery and jump spam filters.

While we have taken various measures to maintain a high server reputation, there are factors beyond our control that can influence email classification. This article outlines the reasons behind emails being flagged as spam and provides solutions to enhance email deliverability.

Google employs artificial intelligence (AI) to classify emails as spam, considering various factors such as server reputation, content of the message, and the email address from which the emails originate.

Server Reputation:

Our team has diligently worked to maintain a high server reputation, which plays a significant role in email deliverability. We regularly monitor our server reputation through the Gmail Postmaster tool and ensure it remains consistently high.

Content of the Message:

Emails can be classified as spam based on various factors, including their content. If the AI algorithm detects elements that resemble spam, it may flag the email. While we strive to optimize our email content, there are instances where customization may be necessary.

Default Email Templates:

Bookem provides default email templates for your convenience, but it's possible that some users have marked these templates as spam. As a result, the Google AI may consider similar messages as spam. To mitigate this, we recommend editing the templates to personalize the content. By rewording the messages, you increase the chances of bypassing the spam filters.

This leaves 3 things that you can change:

Customising Automated Messages:

Consider modifying your appointment-related messages in "Settings > Automated messages" and your invoice-related messages in "Settings > Payments and invoicing." By tailoring these messages to align with your unique communication style, you reduce the likelihood of triggering spam filters.

Email Address Reputation:

The email address from which your emails are sent also influences spam classification. To enhance deliverability, we have made an important change. Emails will now be sent from instead of random email addresses for each client. This allows the Google AI to differentiate and associate a reputation with emails originating from

Encourage Clients to Mark as "Not Spam":

Instruct clients who find your emails in their spam folder to mark them as "not spam." This action is recommended by Google and helps the AI learn that your emails are not spam. By establishing a positive reputation for your email address, future emails are less likely to be flagged as spam.

If spam filters are getting you down, remember that SMS's are more relaible delivery method for important reminders and messages.

A final suggestion: customize email templates for invoices and sendable forms

To further improve email deliverability, another primary method is to edit the content of an email template that consistently lands in the spam folder. This is particularly important for invoice templates. You can customize the content of these templates by following the instructions provided in the article: How do I edit default messages for invoices?

For sendable forms, such as intake or consent forms, you can also customize the content to improve deliverability. Learn how to automatically send client intake forms and make necessary edits in this article: How do I send client intake forms automatically?
