"Free" in B2B software is rarely truly free; but the best platforms offer free tiers that are genuinely useful and not just bait to force an immediate upgrade. The tools worth considering at zero cost give you real functionality: actual contacts, actual sends, actual automation. The upgrade path should be visible and fair, not a cliff that hits you on day 31.
