Amplemarket vs SellScale (Selix) (2026): which should you pick?

Pick Amplemarket if

• Fits if you'd rather pay for one tool than a data tool and a sequencing tool separately
• Works for sales teams mixing email, LinkedIn and calls in one sequence

Look elsewhere if

• Pricey if you're on your own, as Startup is $600 a month and is priced for 2 users
• Skip it if you want every price up front, as Growth, Elite and extra users are quoted by sales
• Tight if you call a lot on Startup, which has 600 phone credits per user a year
• Not for you if you want Duo Voice or AI reply drafts on the entry plan, as they start on Growth and Elite
• Watch out: the 7-day trial is on request with a business email, and Startup is an annual term

Pick SellScale (Selix) if

• Fits if you want an AI agent to do list building and sending across email and LinkedIn
• Works for a team that can commit for a year before knowing its usage bill

Look elsewhere if

• Not for you if you want to know the price, as per-send rates aren't shown
• Watch out: the page states a 1-year minimum
• Tight if you run more than 1 campaign, 1 mailbox or 1 LinkedIn account on the self-serve plan
• Skip it if you still search for sellscale.com, which now just points to Selix
