Automate domain warming with Daily ramp for newsletters

Previously, you could only set a fixed send rate for newsletters—a consistent number of messages per minute, hour, or day. If you needed to warm up a domain, you had to manually create separate newsletters for each period of your warm-up schedule. Now, domain warming is less manual and easier to set up! We’ve also increased the maximum newsletter send time to 60 days to give you more room for gradual warming and large sends.
