With my extensive experience in email handling and marketing, as well as my expertise in HTML, CSS, and other coding languages, I am confident that I can navigate your email blast campaign successfully. Understanding the importance of your emails being able to reach the receivers' inbox and not get flagged as spam is essential, and it is a challenge that I have the practices and know-how to overcome.
Given that you prefer Gmail for this project but remain open to using third-party applications like Mailchimp, I can carefully guide you through the process step-by-step so that you are equipped to handle similar tasks independently moving forward. However, I am fully prepared to take complete control of sending the emails myself if needed, ensuring every contact receives a personalized message from your personal Gmail account.
Regarding payment terms, we can discuss a fair arrangement based on the complexity of the task. My primary goal here is to help you achieve your desired outcome with ease and efficacy. With my proven track record in optimizing email campaigns for maximum deliverability and viewer engagement, hiring me would bet on a better chance to succeed in getting your messages across to all 400 client emails without a hitch!
