SendHustle Privacy Information: What data does our server store?

Legal·February 22, 2016·By Ajay Goel·3 min read

Many users are concerned about the privacy of their email marketing lists and whether SendHustle stores their email addresses and the contents of email messages, and whether any of this data is shared with third parties. The information below is meant to address these concerns.

Overview of how SendHustle works

SendHustle works by transferring data to and from your Gmail account. Most of this data transfer occurs via numeric identifiers specific to Gmail and the Gmail API. In some cases, email addresses are transferred from the SendHustle server back to the Gmail interface, but in a secure manner over SSL. Gmail does not allow a third party integration like SendHustle to connect to account data without the use of SSL.

How are your email lists used?

In order to track opens, clicks, and provide unsubscribe functionality via the SendHustle unsubscribe link, our database does store the email addresses to which you are sending email. This data is stored in a database, secured by two layers of firewalls, and is never shared with any third parties. SendHustle is similar in this regard to well-known email marketing systems like MailChimp, where storage of email addresses is required to provide standard email marketing features.

Does SendHustle store the content of your email message?

No. Unlike a traditional email marketing service like MailChimp, the SendHustle database does not store the contents of your email marketing campaigns, except for the From Address used for each campaign.

We store the From Address because in Gmail, multiple From Addresses can be authorized for use in a single Gmail account, and by storing the From Address, we are better able to support users by being able to look up their SendHustle account when they tell us they sent a campaign “from” a certain address.

We do not store the content (Subject / Message) of email campaigns, but the content does pass through our server ephemerally. This is required in order to add the mechanisms to an email message that allows SendHustle to track opens and clicks on individual email messages. This process happens in microseconds and the content of an email message does not live on our server beyond that.

Does SendHustle share any of your email list information with third parties?

We may share your email list information with third-party service providers, including advertising platforms such as Google, to assist in delivering targeted advertising campaigns. These third parties are required to use the information only for these purposes and in accordance with applicable data protection laws. We do not sell or trade your email information for any other purposes.

Policy for Mobile Numbers

No mobile information will be shared with third parties/affiliates for marketing/promotional purposes. All the above categories exclude text messaging originator opt-in data and consent; this information will not be shared with any third parties.

Data Deletion Requests

In compliance with GDPR, any user may request that his/her data be deleted from our servers. To make such a request send an email to datadeletion@wordzen.com from the SendHustle account whose data you wish to be deleted.
