Pricing is sales-only with 1-year minimum contracts.
Marketo doesn't publish pricing. You go through a sales process, get a custom quote (usually $1,500-$3,000/mo+ depending on database size and features), sign a 1-year contract, and pay annually upfront. There's no try-before-buy, no monthly billing, no escape if it doesn't fit.
Mailsoftly: published pricing, monthly or annual, no contracts, no sales process
