You asked and we answered. Literally. We have the second half of questions our Deliverability expert Kurt Diver took to answer from our Email Deliverability 101: Best Practices to Master the Inbox webcast last week! Take a gander at the remaining Q&A below and check out the first half of the questions answered by Erik Ault last Friday. Gmail Feedback Loop– How is this implemented? Who has access to it? SendGrid adds a second DKIM record for all emails sent to Gmail.com. This DKIM record tells Gmail to send all spam complaints for this particular sender back to SendGrid. Gmail’s feedback loop is different in that they only provide the email service provider with the aggregate number of spam complaints for the given day. How do we identify recipients who report us as spam? Most ISPs provide SendGrid with full copies of the spam complaint emails. SendGrid parses recipient information from these complaints and adds the email address to your suppression table. SendGrid has a built in feature that can forward all these spam complaints to the sender as well. Can I check my company’s send rating somewhere? Yes! We recommend the following sites: https://senderscore.org http://www.senderbase.org http://trustedsource.org Is there a way to see if we’re blacklisted or on a spam filter? Yes, check out the following tool: http://mxtoolbox.com/blacklists.aspx How do you land on a blacklist? Sending to spam traps or sending malicious email content. Most blacklist operations monitor hundreds of thousands of spam trap email addresses. If you’re sending to spam trap addresses, you’re sending with a rented/purchased list or your sending to an old unengaged list. Do my reputation and “temperature” benefit in any way from an affinity with SendGrid? No, SendGrid’s IPs/clients aren’t given special treatment by the recipient ISPs. We have relationships with many of the ISP and blacklist operations which helps SendGrid when dealing with deliverability issues. Does Gmail advise enabling DKIM or DMARC? Gmail best practice is to use DKIM & SPF. DMARC utilizes both DKIM and SPF, and tells the recipient ISP how to handle email that isn’t properly authenticated. Gmail is rejecting hundreds of millions of emails every week that are impersonating legitimate senders. It is to your best interest to implement DMARC to protect your business reputation. If I set a SPF record to: ‘v=spf1 a mx include:sendgrid.net ~all’ What about general person email sent through a companies usual Exchange servers (none sendgrid emails). By including mx in your SPF records you’re authorizing all your MX servers to send emails. MX – Specifies all A records for each host’s MX record. Example: “v=spf1 a mx include:sendgrid.net ~all” What’s a good click rate? When I assess a sender, I consider anything greater than 5% a good open rate. Not every email has a call to action, and due to safety concerns many recipients will navigate directly to you company website instead of clicking on links within emails.
