We deliver both ongoing and one-off emails as quickly as possible to your selected users. The time it takes to deliver your message is based on two major factors:

We batch message delivery into several logical units of work and each stage is processed on a queue. Messages sent to a smaller number of users get placed into higher priority queues. Therefore, the more targeted your messages are the faster they’ll get delivered.

In the first two hours after a new user is created in your Intercom account, Intercom will check for any emails they should receive every time we receive a ping request. (This should happen each time they load a page in your web app where you have Intercom installed).

After the first two hours, Intercom will check every hour for any emails that users should receive.

For transactional emails, we know these are the most important so they match instantly and send in our highest priority queue – typically within seconds or minutes, however in times of high traffic there can be slightly longer delays.

Yes, depending on the audience type. If you pause a Fixed email, it will have already been sent to the full audience as it sends to the users who match at the time it's set live (assuming it hasn't been scheduled for a future date). Pausing a Dynamic email will prevent the email from sending to any further users at the time it's paused.

No - once an email has been sent, you cannot recall it.

To reactivate your mailings and resolve the issue of hitting spam traps, follow the recommendations listed here. Implement double opt-in into your signup flow, review your message audiences, and make sure you're correctly filtering out email addresses that have not been verified. Once you have made the necessary changes, contact Intercom's support team with the details of the actions you have taken, and we'll review the sending restrictions on your workspace.

It's currently not possible to CC or BCC a participant in outbound emails sent from the Outbound tab. This feature is not planned for the near future however you can upvote, comment and subscribe to this feature request in our Product Wishlist.

If you start an email conversation with a user from the Help Desk, you can CC participants but you cannot BCC.

The audience preview for email messages won't look the same as when you're targeting the same users with a chat or a post message, or if you are filtering them in Contacts.

With email messages, we automatically exclude users that:

The users that are excluded from receiving email messages can be found within your Contacts by using the same filters in your message and then additionally adding Email has any value and Unsubscribed from Emails is true or Marked email as spam is true or Has hard bounced is true.

This should account for the discrepancy you are seeing with the numbers in your audience preview.

There are a few things to keep in mind when using the filter audience from a csv feature:

There are a few ways to do this:

You can opt out a particular user from receiving bulk emails by including an extra option in the intercomSettings snippet:

You can unsubscribe/resubscribe Leads and Users from receiving bulk emails by selecting the specific subscriptions or checking "unsubscribed from all emails" within their profile:

You can unsubscribe Leads/Users directly from the Help Desk when you are chatting with them by going to the 3 dots beside their name in the Lead/User Data Help Desk App 👇:

You can set users as unsubscribed from emails in Intercom by uploading a CSV containing user emails and a second column "unsubscribed_from_emails" with the value true in each row.

Here is an example of what that CSV would look like:

When you import the users, map the Email field, then skip the others until you see "Which additional columns would you like to import".

Choose the column unsubscribed_from_emails , then choose "Create a new custom attribute" from the drop down (ensure it's called exactly "unsubscribed_from_emails"), then give it a Boolean data type. Finally, confirm and import users.

Yes. Leads and Users that are unsubscribed will still receive:

You can start a 1:1 message with by clicking the "New conversation" button within a Lead/Users profile👇:

Intercom helps you to measure success of a message with open tracking, goal tracking and click tracking. These tracking methods help to identify which parts of your message are the most successful in order to optimize future campaigns. Engagement is a good measure of health for your campaigns. Engaged users typically open your emails, click on your links and take the actions you encourage them to take in your message.

Click tracking works by overwriting the link in the body of a message to go through our own portal before redirecting a user to the final destination.

For example, if you paste a link like www.example.com/picardspersonallog, we will transform that into another unique link. When a user clicks the link they are redirected through our domain, where we increment the click counter and then forward the user onto the original destination.

Here’s what the links look like:

Click tracking also allows you to identify leads you've emailed when they follow links to your site.

For example, if you send an email to a new lead: "michelle@example.com" and they click on a link which takes them to your site, they'll be automatically identified with the same email address when they start a conversation in the Messenger. This allows you to greet them with a personalized in-app message, and continue the conversation.

If you do ABM (Account based marketing), you can also be notified directly when the lead visits your site, even if they don't start a conversation.
​
From the Clicked stats on a message, you can see which users clicked links in your message, and the number of times each link was clicked.

Using Intercom you can embed a deep link in your in-app messages or as the URI for your push messages. To enable deep linking for your mobile app please see our Android and iOS Developer Docs for more information.

Universal links are used to direct users to specific iOS mobile apps are incompatible with our current click tracking offering. If you already support universal linking and host your own Apple App Site Association (AASA) file, turning off click tracking will allow you to direct users to specific apps on their mobile device.

You can specify which domains you wish to turn off click tracking for in Settings > Outbound > Customization, under Universal linking.

This feature surfaces in three places in Intercom:

When you’re inserting a URL into an email we surface a header linking to a doc to explain how we track link clicks and how we identify leads who click on these links:

When you’re talking to a person that has been identified in the Messenger by clicking on a link, we surface a small alert icon below the message, with a tooltip that links out to a doc explaining how we identify people and warn of possible impersonation.

Ability to toggle this ON/OFF can be found in Settings > Security under the Data Security Settings tab. It will be OFF by default for existing customers and ON by default for new customers:

Yes, click tracking allows you to identify leads you've emailed when they follow links to your site.

For example, if you send an email to a new lead: "michelle@example.com" and they click on a link which takes them to your site, they'll be automatically identified with the same email address when they start a conversation in the Messenger. This allows you to greet them with a personalized in-app message, and continue the conversation.

If you do ABM (Account based marketing), you can also be notified directly when the lead visits your site, even if they don't start a conversation.
​
From the Clicked stats on a message, you can see which users clicked links in your message, and the number of times each link was clicked.

Your Workspaces ability to identify leads you've emailed based on their email address can be adjusted from within your Workspace Security settings within the Data Security Settings tab, under Lead email identification.

Currently, Intercom does not have click tracking available within articles
