SharpSpring strives to maintain a secure email system for all senders. By limiting potential abuse, we can provide high email deliverability for all good senders. One way SharpSpring maintains security is by proactively checking the sending domain an email is about to use. For example, in the sending address From:firstname.lastname@example.org, SharpSpring would check the domain example.com.
While extremely uncommon, you may receive in-application messaging if the sending domain can not be used.
Some examples of addresses that may be flagged are:
- Domains that may be used for phishing or fraud
- SharpSpring.com or other domains that we as a company use
- Disposable email addresses
- Domains with DMARC reject policies
However, any domain which a customer verifies and authenticates may be used.
