Instantly vs Mailivery (2026): which should you pick?

Pick Instantly if

• Fits if you send from lots of mailboxes and don't want to pay per inbox or per seat
• Works for teams that want warm-up included rather than bought per mailbox

Look elsewhere if

• Skip it if you want LinkedIn steps in the same sequence, as Instantly is email only
• Tight if you stay on Growth, with 1,000 contacts in total, a read-only inbox and no webhooks
• Pricey if you need lead data too, since credits start at $9 a month for 150, and on Growth the CRM is only a 14-day trial
• Watch out: the contact limit is a running total, not monthly, and 25,000 more cost $87 a month
• Watch out: there's no free plan, and the trial stops at 250 contacts and 1,000 emails

Pick Mailivery if

• Fits if you already send cold email and need your mailboxes warmed
• Works for small teams with a handful of mailboxes

Look elsewhere if

• Skip it if you want a tool that sends campaigns, since it only warms up
• Tight if you have many users: seats stop at 2, 4 and 10 across the plans
• Watch out: the yearly Professional card says 600 emails a day, the table says 800
• Pricey if you want more verification credits, which are one-time purchases

Instantly

• There is no free plan; the 14-day trial stops at 250 uploaded contacts and 1,000 emails.
• The uploaded-contact limit is a total across all campaigns, not a monthly one. On Hypergrowth and up, 25,000 more contacts cost $87 a month.
• Lead data and the AI agents need an Instantly Credits plan, from $9 a month for 150 credits; on Growth the CRM is only a 14-day trial.
• Replying from Unibox, webhooks, the CRM and full A/Z testing need Hypergrowth, $107 a month billed monthly.

Mailivery

• Each mailbox is limited to 100 warm-up emails a day on Starter and 250 on Professional and Business.
• Email verification credits are one-time; extra credits are bought inside the platform.
