To improve email deliverability and reduce the risk of your messages ending up in the spam folder, start by configuring proper SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records for your domain. These authentication methods help verify that your emails are legitimate, increasing trust with recipient mail servers.

Additionally, pay attention to your email content. Avoid spam-triggering elements such as excessive links, all-caps text, or suspicious-sounding phrases. Encourage recipients to add your email address to their contacts or whitelist your domain to further boost your chances of landing in the inbox.
