Lead generation from email newsletters for a video editing service

For the service https://eveditor.net/, which provides wedding film editing services, a series of "cold" mailings has been carried out to databases of videographers from English-speaking countries: USA, Canada, Australia, and New Zealand, as well as European countries. A nearly complete cycle of email marketing work has been conducted: (the texts of the emails were provided by the client):
1. The mailing service and postmaster services have been set up.
2. The original email address databases have been cleaned and segmented.
3. Unique design templates have been created for each email.
4. Responsive layout of the emails has been completed.
5. The sending of emails to the prepared databases has been configured.
6. Statistics have been collected and recommendations for improving the mailings have been provided.

The open rate of the emails is 10-35%, ClickRate - 0.5-1.5%, and a sufficient number of inquiries have been received as a result of the mailings.
