As an alternative to the Sendoso Chrome extension, you can create a custom button in Salesforce to complete one-to-one sends. This button can live on any object, however, Sendoso recommends that you place it on the lead and contact objects to pull in recipient information.
**Note - You will need Salesforce admin permissions to complete this setup
To get started, navigate to the Object Manager and search for contact or lead (you'll need to repeat these steps for the other object)
After clicking on that object, navigate to the Buttons, Links, and Actions tab then hit New Button or Link
Next, configure the button details:
Label & Name: Sendoso
Display Type: Detail Page Button
Behavior: Display in new window
Content Source: URL
Here are the URLs configured with default Salesforce fields (if are using custom fields, be sure to change them in the URL):
Lead:
https://app.sendoso.com/v2/plugin/sends?channel=salesforce&name={!Lead.Name}&email={!Lead.Email}&company_name={!Lead.Company}&address={!Lead.Address}&city={!Lead.City}&state={!Lead.State}&zip={!Lead.PostalCode}&country={!Lead.Country}
Contact:
https://app.sendoso.com/v2/plugin/sends?channel=salesforce&name={!Contact.Name}&email={!Contact.Email}&company_name={!Account.Name}&address={!Contact.MailingStreet}&city={!Contact.MailingCity}&state={!Contact.MailingState}&zip={!Contact.MailingPostalCode}&country={!Contact.MailingCountry}
Hit Save to complete the button set up!
Lastly, you'll need to be sure the button is added to the necessary page layouts.
Head to the Page Layouts tab of the object, choose the layout you need to add the button to, and then drag it to the custom buttons section of the layout.
That's it! You now have a custom button in Salesforce to complete one-to-one sends via Sendoso!
