Email channels configure the provider Vero uses to deliver email to your users. Vero includes a built-in email provider so you can start sending straight away, with the option to connect your own ESP for more control over sending domain, IP reputation, and deliverability. ## Preconfigured channels Vero comes with an email channel preconfigured so you can start sending straight away. This channel is named "Vero Mailer" and Vero automatically manages the domain and IP addresses associated with this channel. ## Add a channel Click **Channels** then **Add** next to the channel provider you want to configure. Give your new channel a name, add the required API keys (or other authorization credentials) and select **Save**. Your channel is now available to select when creating a **Broadcast** or **Journey**. ## Setting a default channel When creating a new campaign Vero will default to a specific channel. You can set the default channel by choosing **Mark as Default** within the **Channels** menu. ## Important notes on specific channels ### Custom domain If using the preconfigured "Vero Mailer" channel, your emails will look something like this: vero.test-email-unverified-domain Email clients will show as being sent "via veromailer.com" (or similar) because the domain of the **from address** used to send the email (e.g. `chrishexton.com`) does not match the domain of the server that sent the email (e.g. `getvero.com`). The **Custom Domain** channel type enables you to send emails using your own domain, removing the mismatch and "via veromailer.com" message. ### Requesting DNS records Select **Add** next to the **Custom Domain** channel type. Name the channel and add the **Domain** you'd like to send from. Vero will generate the DNS records you need to add to your DNS host. Once you've added the DNS records to your host return to Vero and select **Verify domain**. Vero will test to ensure your DNS records are visible. Once verified you will be able to send using your newly configured channel. #### Custom subdomains for link tracking By default Vero will generate tracking links using the subdomain "email". For example, if you configured the domain `mydomain.com`, we'd rewrite links using the subdomain `email.mydomain.com/c/tracking-url-here` You can email our support team to request that we use a different subdomain for link tracking. ### Sendgrid #### Webhooks When configuring Sendgrid as an email channel Vero will add an event webhook entry in order to sync message interactions back to Vero. Sendgrid only supports one event webhook. As a result, if you have already configured a webhook Vero will **not** install its webhook. In this scenario Vero will only be able to record "Sent" history in **Logs** and **Reports**. #### IP Pools Vero supports Sendgrid's [IP Pools](https://docs.sendgrid.com/ui/account-and-settings/ip-pools). You can add a single IP Pool per Sendgrid channel configuration in Vero. ### Mailgun #### Webhooks When configuring Mailgun as an email channel Vero will add an event webhook entry in order to sync message interactions back to Vero. This will be added in addition to any event webhooks you have already configured in Mailgun. ### Mailjet #### Webhooks When configuring Mailjet as an email channel Vero will add an event webhook entry for each event type in order to sync message interactions back to Vero. Mailjet only supports one event webhook per event type (e.g. "opens", "clicks", etc.) As a result, if you have already configured a webhook for a specific event type Vero will **not** install its own webhook for that event type. In this scenario Vero will not be able to record the history for that event type in **Logs** and **Reports**. ### Mandrill (Mailchimp Transactional Email) #### Webhooks When configuring Mandrill as an email channel Vero will add an event webhook entry in order to sync message interactions back to Vero. This will be added in addition to any event webhooks you have already configured in Mandrill.
