If you're sending through these providers, please use those integrations instead of SMTP. **Gmail Sync:** [Two-Way Email Sync for Gmail](https://docs.ghlcustomercare.com/docs/integrations/other-integrations/connect-google-to-use-gmail-for-email) **Outlook Sync:** [Two-Way Email Sync for Outlook](https://docs.ghlcustomercare.com/docs/integrations/other-integrations/two-way-email-sync-for-outlook) **LC Email:** [What is LC Email?](https://docs.ghlcustomercare.com/docs/email/lc-email/what-is-lc-email) If you choose to use SMTP, you do so at your own discretion. SMTP is an advanced use case and not how most users should send email through GHL Customer Care. Support is provided on a best-effort basis. ## A List of SMTP and IMAP Servers Use the reference below to look up the SMTP and IMAP server settings for your email provider:  [? SMTP & IMAP Server Reference List](https://www.arclab.com/en/kb/email/list-of-smtp-and-imap-servers-mailserver-list.html)  ## Sender Email Address Configuration Limitation If you are using an SMTP provider, make sure the sender email you mask here **matches the email you integrated with**. [Learn more on how to configure the sender's email address here](https://docs.ghlcustomercare.com/docs/email/general-2/sending-priority-from-name-address). ? If the sender's email does not match the SMTP integrated email, or if the sender's email is not verified with your SMTP provider, the email **will fail to deliver**. ## How to Test Your SMTP Integration When sending an email, update the sender's email address so it matches the integrated SMTP email. In manual conversation, the sender email defaults to your login email. You'll need to change it to match the SMTP integrated email. By default it will show your login email: ![SMTP sender email configuration screenshot](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/155029827288/original/gnPwP2x5q8zEvsCuFGHt1QHIQlamElUaEA.jpg) **How to Test Your SMTP Integration (image 1 of 3)** This screenshot appears in the "How to Test Your SMTP Integration" section of "Setting Up SMTP Providers".

[Gmail, for example, limits approximately 100–150 emails per day](https://support.google.com/a/answer/166852?hl=en) when connected via a remote email client. [Why Can't I Use My Free Email Address As The SMTP? →](https://docs.ghlcustomercare.com/docs/email/smtp-providers/why-can-t-i-use-my-free-email-address-as-the-smtp) ## Workflow / Email Statistics Via SMTP, we currently receive only **sent**, **open**, **click**, and **bounce** events. A **delivered** event is not available from the SMTP provider. ℹ️ Because of this limitation, the system marks an email as **delivered only after an open event is received**. We highly recommend [setting up Mailgun or LC Email](https://docs.ghlcustomercare.com/docs/email/mailgun/step-by-step-guide-to-set-up-mailgun) to get full sending statistics. Learn more about [Troubleshooting Email Stats](https://docs.ghlcustomercare.com/docs/email/troubleshooting-email/troubleshooting-email-statistics). ## Why SMTP Emails Are Stuck in "Sent" Status With SMTP, we only receive **sent**, **open**, **click**, and **bounce** events. A **delivered** event is not available from the SMTP provider. Because of this limitation, the system marks an email as **delivered only after an open event is received**. That's why the email initially shows as **sent**. Once the recipient opens the email, the status updates accordingly. ## Common Issues When Setting Up SMTP Providers Make sure [1Email Re-Billing](https://docs.ghlcustomercare.com/docs/saas-configurator/saas-mode/email-re-billing-on-the-unlimited-297-2970-and-pro-497-4970-plans) is **disabled** while making changes to the default provider.
