If you ever run into an issue where your emails are going into your recipient's SPAM folder, read on for several tips:
SPAM false positives are inevitable
Before we go too far into the suggestions, it's important to realize that as long as there is spam, there will be false positives. It doesn't matter what server you send through, whether every 'technical' detail is correct, or the content of your email. Spam filters can be configured to be too hyper-aggressive and result in false positives. It's impossible to prevent this from happening 100% of the time, but we can get minimize this by following a few common sense rules.
Don't use free email addresses
This means that if you’re sending email "from" a free/disposable email address (@yahoo.com, @aol.com, @gmail.com, @hotmail.com etc) your email will be flagged as spam or rejected outright more frequently. This is due to how these free domains are configured and restrictions placed on their servers.
We recommend that you choose a “from” address that is associated with a domain you control rather than a free domain (e.g., example@companyname.com rather than example@yahoo.com). This not only limits any deliverability issues, it also gives your business the legitimate exposure it deserves.
If you have no other choice than to use a free webmail domain (e.g., Gmail, Hotmail), then create a support ticket and we'll create a special email account for you.
This only refers to your domain name (the part after the @) If you're using yahoo or gmail behind the scenes, it doesn't matter as long as your address isn't @gmail or @yahoo etc.
Configure your Domain
There are a few changes you'll need to make to your domain to maximize your deliverability. Instructions for that can be found here
