How to minimize the amount of bounced emails?

To minimize the amount of the bounced emails from your campaigns, it is necessary to set up a SPF record on your sending domain.

What is SPF? 

Sender Policy Framework (SPF) is a method of fighting spam. As more time passes, this protocol will be used as one of the standard methods of fighting spam on the Internet. An SPF record is a TXT record that is part of a domain’s DNS zone file. The TXT record specifies a list of authorized host names/IP addresses that mail can originate from for a given domain name. Once this entry is placed within the DNS zone, no further configuration is necessary to take advantage of servers that incorporate SPF checking into their anti-spam systems. This SPF record is added the same way as a regular A, MX, or CNAME record.

What is the SPF record that I need to install? 

Here is the SPF record that you need to set up on your sending domain:

V=spf1 +A +Mx +Ip4:72.52.238.74 ~All

How to set up the SPF record on my domain?  (ex.: GODADDY) 

1. Log into your Domain Management Account
2. Go to Domains:

3. Next to the domain you want to manage, under the Action section, click on the Manage DNS button:

4. At the bottom of the Records section, click Add and select TXT from the menu.

5. Complete the following fields:

• • Host – Enter the host name for the TXT record. For example, type @ to map the record directly to your domain name, or enter the subdomain of your host name (labeled Host), such as www or ftp.
  • TXT Value – Enter the value you want to assign to the record.
  • Select how long the server should cache the information. This is called TTL (Time to Live).

For a TXT SPF record, enter the SPF rule in the TXT Value field:

V=Spf1 +A +Mx +Ip4:72.52.238.74 ~All

6. Click Save to commit the changes.

Note:

 The usage of public email domains like gmail.com, hotmail.com, yahoo.com, aol.com, etc leads to high numbers of bounces. Please use the proprietary domain names for emails like [email protected] VS [email protected].
