We shut off mass emailing options a long time ago. We are getting issues with the anti-Spam regulations as well as getting our email servers flagged as "Spammers" as people were "abusing it". There are vendors that are much better equipped to handle your campaigns (even for free).
We recommend, exporting a list into an Excel then creating a mailing list and campaigns in a place like MailChimp (https://mailchimp.com/) They track responses and most of your emails will be delivered (as opposed to going to Junk) as they are white-listed with major email providers.
To export a list from Nowcerts, just go to Insureds or Prospects, use the filters to select the records you want and click "Export to Excel". The resulting Excel file will have email addresses. Convert that to ("Save as") CSV and import to Mailchimp.
We have added integration with Mailchimp, you can now export the list directly to MailChimp (look under Miscellaneous, Data Import/Export, MailChimp). However, be aware of one main difference.
If you import a mailing list from a CSV file to Mailchimp, it is considered a "manual" mailing list.
If you use the integration to send a mailing list to Mailchimp, it is flagged as "Machine generated". They are then required to email every single record on that list asking them to confirm that they want to be on that distribution list. So, please chose the option carefully.
I hope this helps!
