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

Pick AiSDR if

• Fits if you're a founder who wants outbound running without hiring an SDR
• Works for HubSpot users who want every email and reply logged back to the CRM

Look elsewhere if

• Pricey if you contact lots of people on your own, as every person prospected costs $1.50
• Not for you if you run Salesforce and want to skip the sales call, as its sync is on Team plans only
• Skip it if you want to try before paying anything, as there's no free plan or trial on record
• Watch out: a look-alike sending domain is $33 a month, and InMail needs your own Sales Navigator account
• Tight if you want a fixed bill, as self-serve is charged daily and Team plans run on quarterly contracts

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
