Email Deliverability

Close uses your email server for email delivery, but we get a lot of questions from customers on how they can ensure their emails get delivered to their prospects and aren't caught by a spam filter.

Learn some tips and tricks for sending sales emails and getting responses

Here are some common things you can do to help avoid being flagged as spam:

Inside Close

  • Make sure the template you're using doesn't have any crazy formatting and doesn't use things like all caps or a lot of explanation points in the subject line / email body.
  • If you are still getting issues, try disabling the Close application open tracking pixel and see if that makes a difference. Some email servers identify hidden pixel images and prevent those emails from being delivered.

Outside Close

What are SPF, DKIM, and DMARC?

Sender Policy Framework (SPF) records allow domain owners to publish a list of IP addresses or subnets that are authorized to send email on their behalf. The goal is to reduce the amount of spam and fraud by making it much harder for malicious senders to disguise their identity.

DomainKeys Identified Mail (DKIM) standard is an email authentication technology that verifies a message was sent from a legitimate user of an email address. Itโ€™s a way to additionally sign your emails in a way that will allow the recipientโ€™s server check if the sender was really you or not.

Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication method that allows you to protect your email domain from spoofing.
