mass email to all customers with a pdf attachment

AI generated answer (using internal Slack threads):

To send a mass email to all customers in your organization, you have a couple of options: 1. Send Email Mass Update: This is a built-in feature in NetSuite that allows you to send a mass email to a list of recipients. You can customize the email content and subject line. 2. Email Marketing Campaign: This is another built-in feature in NetSuite that allows you to create and manage email marketing campaigns. You can target specific groups of customers and track the effectiveness of your campaigns. 3. Mail Merge: This is a process of creating a batch of personalized emails using a template and a data source (like a saved search). You can use this method to send a mass email to all customers. 4. Saved Search: You can create a saved search of your customers and use the 'Message' tab to write an email or attach a PDF. As for sending invoice PDFs, it is generally considered best practice to send invoices as PDF attachments in emails. However, if you're experiencing deliverability issues, you might want to consider sending a HTML invoice that contains a link to the PDF for the customer to download. Make sure you have DKIM set up correctly to avoid mail delivery issues. Also, ensure your DNS is good and consider excluding watermarks in your PDFs as they can get flagged by some spam filters. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
