You've made a beautiful Queue and sent it out to your users, but no one received it. What can you do to improve deliverability?

Have Your IT Department Whitelist Our Sending Addresses

If emails end up in spam folders or get caught in quarantine by your spam filter you may need to whitelist our email address. We have multiple addresses to be whitelisted, but depending on your spam filter you may only need one. 

Whitelist By Reply/From Address

ALL Clearview Social application emails come from, all the time, every time. Talk to your IT department about whitelisting the above address. If you don't know how to ask for this, use the Intercom Chat in the lower right-hand corner of Clearview Social to start a conversation with us, and if you can introduce us to the right person from your IT department, we'll take it from there. 

This is our preferred method for whitelisting for most spam filters. This is all it takes to get us out of the spam filter and into your inbox. If emails still fail, usually for services like Proofpoint and MIMEcast, trying the next method should solve the issue.

Whitelist By Envelope Sender

Some filtering services like Proofpoint filter based on the envelope sender instead of the from address. If your filtering service does this you may whitelist any email with an envelope sending address starting with "bounce-md_30273915" as this uniquely identifies our application.

Our preferred method for whitelisting the envelope from address is to whitelist our return URL domain "". All emails we send have an envelope sender address similar to the one below:

bounce-md_30273915 - Identifies our application
577ec92a.v1-757231009ae04bf08d9d5417526fbab4 - Identifies the email - Our signature return domain

By IP Address 

Because we send from Mandrill by MailChimp's shared pool, we cannot guarantee a single IP source for our emails. If whitelisting by address is not enough and whitelisting by IP is your only option, please follow Mandrill's best advice for whitelisting their entire shared pool (which is not recommended, but still possible).

Ask Away, We'll Always Answer

We use Mandrill by MailChimp to send all our emails, and one excellent feature of Mandrill is 100% accurate deliverability logs going back thirty days with on-demand resend going back 48 hours. We are always listening in the Intercom Chat in the lower right corner of Clearview Social and if you ask for an update on your Queue's sending status, we have access to up-to-the-second information on the delivery status of every single email.

(Above is an example of the sort of data that our team has access to. If you have a user who is having difficulty receiving a queue, simply ask and we'll check the above—with accurate deliverability receipts and on-demand resends.)

On every page of Clearview Social, the Intercom Chat window is ready to open. We are happy to help.

Important information for us to know

When opening a ticket about email deliverability, to speed up resolution time please include email provider and spam filtering service being used.
