Are there email marketing services that allow you to embed images via Content-ID?

Question

Email Marketing

There is a task: to organize periodic marketing mailings, recipients are employees of companies that use Outlook. Hence the requirement: images in the email must be embedded using the Content-ID so that you do not need to click on the image download button.
I went through a bunch of services, such as MailChimp, SendGrid, SendInBlue... Some of them provide the ability to send emails with embedded images, but only transactional ones. Those. you cannot build a campaign, measure its performance, make unsubscribe lists, etc.
Is there a service in nature that allows you to do marketing mailings with images? It is better, of course, to allow you to add a template through the web interface, but the API option will be quite acceptable.
