The real difference
Instantly sends the emails you decided to send to the people you decided to reach. It does not research your market, find the audiences you haven't thought of, write to a doctrine grown from years of campaigns or read replies against your brief. Even with its AI agents switched on, you remain the operator: you choose the settings and daily limits, connect or buy the inboxes, and answer for the results.
SLSBMB AI starts earlier and covers the whole chain. Your AI Outreach Playbook decides who to reach and why, with a size estimate for every audience, and writes every email. AI Contacts finds and verifies the business emails. The Sending Engine includes infrastructure we own and operate: at $800 a month that is 2 domains and 8 inboxes sending 120 campaign emails a day after a 21-day warmup, and the budget scales in published steps up to $100,000.
The infrastructure is where most of the difference in delivery comes from. Our inboxes sit on our own servers and IP addresses, at most 60 per IP, and warm up through AI-written business conversations between inboxes we operate, checked at the major mail providers; see how our warmup works. Every campaign email varies in wording while keeping its meaning, so mail providers never see thousands of identical messages.
If you already use Instantly
- Keep what you've built. The playbook and the contacts you buy from SLSBMB are yours to export into Instantly or any other tool.
- Compare by the result, not the subscription. Run both on one offer and the same markets for three months, and count targeted replies from the right people and the full cost of each, including your team's time. Our guide on choosing an outbound provider shows how to keep that comparison fair.
Frequently asked questions
Is SLSBMB AI an Instantly alternative?
Yes, if you want outbound done for you. Instantly gives you a sending platform to operate; SLSBMB AI delivers the research, the emails, the verified contacts, the warmed infrastructure and the sorted replies.
Does SLSBMB AI include the domains and inboxes?
Yes. Every Sending Engine budget includes dedicated sending domains and inboxes that SLSBMB registers, sets up with SPF, DKIM, DMARC and MTA-STS, and warms for about 21 days. The first campaign emails go out on day 22.
Can I connect my Instantly or pre-warmed inboxes?
No. We don't connect inboxes whose history we can't see: one bad history can hurt the shared infrastructure every client sends from. Every inbox in the Sending Engine is built and warmed by us.
How much does sending cost per email?
At full capacity, SLSBMB's Sending Engine costs about $0.303 per campaign email at $800 a month and about $0.076 at $10,000, with contacts included. A sending platform's software costs less per email, but the domains, inboxes, contacts, copy and operating time come on top. See what cold email costs for the full comparison.
