Prevent Emails from Going to Spam

Prevent Emails from Going to Spam

Internet Service Providers (ISPs), like Google, Yahoo, and Microsoft, use different types of authentication as a way to scan incoming emails for spam. Emails that fail this authentication are more likely to end up in a spam or junk folder. Because Launchmetrics is sending emails on your behalf, emails sent from the system look "unsafe" to recipients unless authentication is in place- especially to email addresses associated to big corporations who have their own set of email security in place. In these situations, emails are even more likely to end up in spam. To ensure your emails reach your recipients’ inboxes there needs to be a custom authentication that denotes Launchmetrics as a "safe email sender".

You have 3 different types of authentications that you can put in place:

  • SPF
  • DKIM
  • DMARC

SPF

SPF is a DNS record that you will need to input in your public DNS server, with a list of mail servers that allows you to send mail, with your domain name.

Do you have an SPF?
1. Inspect your mail addresses and see what your domain is (everything following an @ symbol). If your mail addresses are xxxxx@clientname.com, then clientname.com is your domain.

2. Use a browser to access http://www.kitterman.com/spf/validate.html


3. Place your mail domain and press "Get SPF Record".
You may receive 2 responses (see below).

  • If you already have an SPF record:
    "Found v=spf1 record for clientname.com:
    v=spf1 …………………………... -all"

  • ​If you don't have an SPF record:
    "No valid SPF record found of either type TXT or type SPF"

If you DO have an SPF, please scroll down to the “Modify your SPF” section below.
If you DO NOT have an SPF, please scroll down to theCreate a SPF” section below.

 

Modify a SPF Record

  1. Log into your Public Domain Name Server (DNS) Administration console.

  2. Look for a page that will let you add or modify records for your DNS.

  3. Modify the TXT record adding include:_shortspf.launchmetrics.com to you record, before the ~all or -all.  Example: v=spf1 a mx include:_shortspf.launchmetrics.com ~all. Use -all to instruct AntiSpam engines to reject all mail that came from an unauthorized server. Use ~all to instruct AntiSpam engines to get the messages but send them to SPAM when they came from an unauthorized server.

  4. Test the new SPF record before saving your records using the Kitterman tool found at: http://www.kitterman.com/spf/validate.html

  5. Save your records. (This modification may take up to 48 hours to spread internally).

Create a SPF Record

  1. Log into your Public Domain Name Server (DNS) Administration console.

  2. Look for a page that will let you add or modify records for your DNS.

  3. You may need to enable advanced configuration.

  4. Create a type TXT record with next text: v=spf1 a mx include:_shortspf.launchmetrics.com ~all.  Use -all to instruct AntiSpam engines to reject all mail that came from an unauthorised server. Use ~all to instruct AntiSpam engines to receive the messages but send them to SPAM, when they came from an unauthorised server.

  5. Save modifications. (This modification may take up to 48 hours to spread internally).

DKIM

DKIM adds some data to your mail, not visible to end user, that allows verification of the message and sender mail address, against tampering in transit.

Create a DKIM Record

  1. Log into your Public Domain Name Server (DNS) Administration console.

  2. Look for a page that will let you add or modify records for your DNS.

  3. Add a TXT record named: launchmetrics._domainkey

  4. Contents of this record follow:

    v=DKIM1; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDEczMKg4bYi128ciAsG/EwAAE7PLukxch3laKGzUykoeZ0B1KiOcNpKgpDFNBgXTtyEXuhaEpTA3DnhDriQjmGMLUW0BC5ONy+aVtm4r9TyE0sejnpZ2PeRs5EaOOfHtZfUD6I+GjI0LrPr7JaOsddMvzX+UCvLt9NTVC55xGHJQIDAQAB


    Side Note: After the semicolon there is a space, but line splitting engine in word processor creates a newline. Test the records using the tool found at: http://mxtoolbox.com/dkim.aspx

 

DMARC

Based on SPF and DKIM, it gathers information to help AntiSpam engines to consider whether mail is likely to be sent to SPAM or not, or even reject a message.​ DMARC can be enabled to send reports about mail rejection and test failure, to domain owner, in order to be aware about third party spammer spoofing your domain or third party forging mails from your domain.


Create a DMARC Record
Dmarc impacts your whole company, therefore this should be done by your I.T team to ensure the record creation is beyond the scope of this document.

  • DMARC is something that is enabled ONLY on your side.

  • Since it will impact your whole companies mail it should be set up by your I.T team to ensure
    record creation is beyond the scope of this document.

  • Launchmetrics requires that you are willing to adopt DMARC, allowing you to place both the DKIM register and the DMARC register in the Public DNS.

  • Follow the steps in previous pages (Create DKIM Record) to make sure the DMARC test will PASS when your recipients receive their mail.
