Who each tool is for
Instantly

Why pick it: Built-in lead database (SuperSearch) eliminates the need for a separate data provider. Deliverability toolkit is best-in-class for the price.
Watch for: If you need multichannel outreach beyond email (LinkedIn, phone), lemlist or Reply.io cover more channels.
VeriMails
Strong Choice
Best for: Consultants doing cold outreach who need to clean lists cheaply before loading them into Instantly, lemlist or a CRM.
Why pick it: Among the cheapest credible verifiers. Credits never expire, so occasional outbound campaigns don't pay for a subscription they won't use.
Watch for: If your outreach tool already verifies (Argorant, Apollo, Instantly), a separate verifier is redundant.
