The "no warm-up needed" claim is bold - curious what's actually
happening under the hood to build sender reputation on a brand new
domain from day one, since even dedicated IPs typically need some kind
of gradual volume ramp to avoid spam folder placement. Would love a
clearer breakdown of the DNS setup process (SPF/DKIM/DMARC) for someone
managing dozens of domains at once - that's usually where the real
time sink is, not the sending infrastructure itself.
