https://community.hubspot.com/t5/APIs-Integrations/API-error-This-hapikey-does-not-have-proper-permissions/m-p/229371#M8267 <P>Hi <A class="mention" href="https://community.hubspot.com/u/peggy_graham">@Peggy_Graham</A>,</P> <P>Using the Email API (which includes the email subscriptions API) requires access to the paid Marketing product. Email subscription status is a part of the Marketing email tool, and doesn’t apply to the Sales product. Sales emails can still be sent to opted out contacts, since they are 1 to 1 emails sent via a connected inbox instead of 1 to many emails sent via the HubSpot marketing email platform.</P> <P>If you have contacts that have requested they not be contacted by sales people, your best bet would be to create a custom contact property (e.g. “Do not contact”) that reflects this desire so that your salespeople can see who they should/should not email.</P> Tue, 20 Feb 2018 18:49:42 GMT Derek_Gervais 2018-02-20T18:49:42Z
