Email deliverability is the biggest issue that needs to be handled. Sendloop performs all available procedures to maximize your email deliverability. However, you can even increase your deliverability rate by making a few changes in your domain DNS zone.

To complete the steps described in this article, you need to have access to DNS zones of your domains you use as from email address.

SPF/SenderID settings are quite important and plays a big role on detecting your email as spam/junk or legitimate. This setting can easily be added to your domain by accessing its DNS zone and adding a TXT record with the following command:

TXT v=spf1 mx ptr include:sendloop-1.com ~all

The above line tells the recipient mail server that Sendloop servers are authorized to send emails on behalf of your from email addresses.

Leading email services such as Hotmail and AOL checks your domain SenderID settings to decide if your email is valid or not. So, we strongly recommend you to set this setting for your domains which are used in from email headers of your newsletter campaigns.
