Once you are sending a significant amount of emails, you will need to pay an email service provider to act as the final delivery system for OneSignal Email Messaging. However, since OneSignal Email Messaging provide marketing email capabilities on top of transactional email providers, you will only need to pay the much cheaper transactional email rate rather than the rate typically charged for marketing automation tools.
Since OneSignal does not act as it's own email service provider, you will need to sign up for one. See above.
Email and push subscribers will have separate OneSignal Player IDs. This is to manage the case where a user opts-out of one you can still send them messages to the other.
If you want to tie emails to push subscriptions, you can to do so with OneSignal Data Tags or you can use the External User Id option.
To configure email, you will need to modify your domain's DNS records. Different email service providers have different requirements for which records need modifying, which likely include MX, CNAME, and TXT types.
You can modify your DNS records where you have your domain hosted. Links to guides on how to do this for some of the most popular hosts are below:
DNS records may take up to 48 hours for changes to propagate across the internet.
Webhooks allow access to email delivery statistics, and are sent from your email service provider to OneSignal. To simplify setup, OneSignal will automatically configure Webhooks when possible with your email provider.
If you already have an active Webhook, you must first disable it in your email service provider before you're able to continue. Webhooks are often used for things like analytics integrations. Contact us for possible workarounds.
Generally yes - a lot of work has been put into ensuring maximum compatibility and visual similarity across major email clients including gmail, Outlook, yahoo mail, and more.
Every email sent through OneSignal must include an unsubscribe link to allow users to opt-out of future mailings. These links may be added in the composer (see Unsubscribe Link), or may be added when sending an email through the API by including
[unsubscribe_url] in the
href= portion of an
<a> tag, like this:
<a class="Unsubscribe--unsubscribeLink" href="[unsubscribe_url]" target="_blank" style="font-weight:600;text-decoration:none; color: #555555;">unsubscribe</a>
The exact unsubscribe link will vary depending on the email service provider you've selected. Some, like Mandrill will redirect users to a OneSignal page that tells users have successfully unsubscribed, while others will handle the user flow of unsubscribing themselves.
Sending emails to push notification subscribers requires two things:
You have the email address to send to
You know which push notification subscriber is associated with that email address
Email addresses are not collected when users subscribe to push notifications. The only way to send emails to subscribers is if you collect email addresses directly from users that already subscribe to (or will later subscribe to) push notifications.
If your app or website collects email addresses, you likely already have an association between emails and subscribers (technically between email and Player ID). In this case, you can use the
setEmail method to add an email address to an existing subscriber. You may also bulk import email addresses that are associated with Player IDs. We recommend both.
If your app or website does not collect email addresses, you will need to do so in order to send emails to your push subscribers. See What are ways I can collect user email addresses? (below).
If you currently have email lists with your current provider, you can export that list to CSV. In the CSV file, the columns should read:
email, list_1 where
list_1 can be whatever you like to help associate those emails with the given list. This will be the Data Tags Key
Then under the
list_1 column you can use "true" or "1", this will be the Tag's Value.
OneSignal's email delivery is sent through a 3rd party provider such as Mailgun, Mandrill or Sendgrid. So we are bound by any limitations of those services. Mailchimp has a very helpful article on this.
Generally, being marked as spam happens when your company is put on a deny list from the ISP, and therefore all emails are marked as spam. You will want to work with your ESP to figure out which deny list your are on and then work with the ISP to get removed.
Here are some helpful policies and procedures:
- Sendgrid's denylist policy and procedures
- Mailgun's Blacklisting policy and procedures
- Mandrill / Mailchimp rejection lists

There are several ways an app or site can gather user email addresses. The most important thing to keep in mind is that you must get a user's consent to send them email, otherwise users will often treat your emails as spam. In many jurisdictions gathering email without consent is also not legal.
The following are some tips on how to request user consent for email:
If you use Facebook authentication
Depending on your implementation, you may already get email when using Facebook to authenticate users. This requires the email permission, which presents users a permission prompt for them to accept. We recommend adding an explanation as to why you need the user's email address when requesting permission (see Facebook's Requesting & Revoking Permissions doc).
If you use Google Sign-In in an Android app
If you use Google Sign-In in an Android app, you may have access to the user's email by using the
getEmail method. The same caveats about getting permission above apply.
If you have an Android app
Android supports additional permissions to get the device's primary email address. See this StackOverflow answer for two ways to do so. Unlike the Facebook method, it's the app developer's job to ask users for permission before getting the device email, and note that Google is likely to shut down apps that do not present users with a clear indication and permission that you wish to send them email.
Ask for email
You can prompt users to enter their email address to sign up for updates, a newsletter, etc. When doing so, if the user already has push permissions, you can associate their Player ID with the email address you collect. As always, we recommend finding ways to add value for users when asking for email, such as getting updates on things they may care about.
If you do not have Identity Verification turned on, you can use the Add a device API method which will create a new email record. If you want to delete the old record, you can do so within our dashboard or API. See Delete Users for more details.
