How To Add a 3rd Party Email/SMTP Account

SMTP ("Simple Mail Transfer Protocol") is the method of communication for emails, which allows you to use the email service within Referins. Setting up your Email/SMTP provider will allow you to send out workflows and more. We recommend using Referins, but you may want to use another provider such as Gmail, Outlook, or other. Follow these steps to get your SMTP setup:

Navigation

Step 1: Adding the 3rd Party

• Navigate to Settings > Email Services.
• Click Add Service

• Choose Other
• Fill out items in the pop-up

• Use the following link to determine the SMTP Provider and SMTP Port Number specific to your integrating service. Use outbound options (not inbound): https://www.arclab.com/en/kb/email/list-of-smtp-and-imap-servers-mailserver-list.html
• Save. 

Troubleshooting Tip: Ensure you approve any verification emails sent to your inbox as Referins attempts to integrate with your email platform. If you are receiving an error message, this is often the cause. 

NOTE: If you're using Gmail, Yahoo, or Outlook as your SMTP provider, please be advised that you may experience some emails being flagged as spam or not being sent out at all.

• If your SMTP provider is set to "TestEmail@Gmail.com" and in your workflow configuration, you try to use a different Gmail account like "[email protected]", Gmail will often flag it as spam.
• If your SMTP provider is set to "TestEmail@Outlook.com" or "TestEmail@Yahoo.com" and in your workflow configuration, you try to use a Gmail account, Yahoo and Outlook will often prevent the email from even sending.
• If you are going to use Gmail, Outlook, or Yahoo as your SMTP provider, use the same email address for your workflows so you don't experience issues.
• Some providers limit the number of emails that can be sent daily. For example, current Gmail limitations allow for about 150 maximum emails daily.

FAQ’s

1. Are there any sending limits when using Gmail as an SMTP provider?

• Answer: Yes, Gmail has sending limits, typically allowing up to 150 emails per day. Exceeding these limits can result in emails not being sent or flagged as spam. Be mindful of these limits to avoid disruptions.

2. Can I use different email addresses in my workflows if I’m using Gmail, Outlook, or Yahoo as my SMTP provider?

• Answer: No, it is recommended that you use the same email address for both your SMTP provider and workflows. Using different email addresses can lead to emails being flagged as spam or blocked entirely by these providers.

3. How can I find my email service's correct SMTP provider and port number?

• Answer: You can find the correct SMTP provider and port number for your email service by visiting the link provided: Arclab SMTP Server List. Make sure to select the outbound options for SMTP settings.

4. Does Referins receive email statistics from all SMTP providers?

• Answer: No, only Mailgun reports statistics back to Referins. Other SMTP providers do not report some or all email statistics, which may limit your ability to track email performance directly within Referins.

5. What should I do if my emails are not sent out when using Outlook or Yahoo?

• Answer: Ensure that your SMTP provider email address matches the email used in your workflows. If you use different addresses, Outlook and Yahoo may block the emails from being sent. Adjust your configuration to use the same address for both.

6. Why is Referins recommended as the preferred SMTP provider?

• Answer: This is recommended because it directly provides email statistics into the platform, offering better performance tracking and fewer issues with email deliverability compared to other providers.

7. What should I do if I reach the daily sending limit on my SMTP provider?

Answer: If you reach the daily sending limit on your SMTP provider, you should pause your workflows and wait until the limit resets. Alternatively, consider upgrading your SMTP provider’s plan to increase your sending limits.
