As Hypothesis I want to be able to email users a link to opt-in to being contacted.

_Justification:_

In our database we currently have over 70,000 registered users but no way to contact them directly via email as they didn’t opt-in explicitly to being contacted via email. In addition to the user story 1.2 to be able to capture opt-in preferences during the sign up form, we need to find a way to gather and up-date the opt-in preferences of existing users.

**Acceptance criteria:**

Done when:

- [ ] TBD

**Details:**

Possible suggestions for ways to email our 70,000+ users:

- To use our current mailing list services e.g Mandrill to send out an email to users.
- To investigate a new mail service or method to send out an email to reach our entire user base e.g Sendmail although the issue with the DIY mailshot approach is we will be blocked by spam filters as opposed to making ourselves known as a trusted organization which sending via a trusted mail client should offer.

_Suggested body copy for email:_

Dear valued user,
As part of our desire to improve our communication with existing users of Hypothesis we are sending this email in order to give you the option of opting-in to being contacting for future product announcements or to ask for your opinion or feedback.
