Outfunnel allows you to send one-off campaigns and automated sequences natively. We recommend using Outfunnel's native email tool for simple personal-looking email campaigns (aka conversational emails).
While you can also use Outfunnel to send designed email campaigns through our custom HTML importing feature we recommend using marketing tools like Mailchimp or ActiveCampaign for campaigns where you'd need to frequently edit the contents of richly designed templates or where you'd need to use advanced features like AB-testing.
Whether you use our native email feature to send campaigns, or use our App connector to connect other marketing tools, Outfunnel can sync email engagement data back to your CRM, use email events for calculating lead scores and use email clicks to initiate web tracking.
We're constantly improving our native email tool as well as adding new 3rd party marketing tools to our App connector.
