Monthly list prices on monthly billing; .com domains at $13 a year spread over 12 months.
With Outreach2day mailboxes on both: $206 on Instantly and $466 on Apollo at 1,000 a day, $727 and $2,209 at 5,000, $1,358 and $4,300 at 10,000. Apollo is priced on Organization, $119 a seat billed annually, because it links 15 SMTP mailboxes per user against 5 on Professional.
Apollo links unlimited Google and Microsoft mailboxes per Professional seat. If your mailboxes are Google Workspace, one $99 seat can hold them, but Apollo's warm-up then costs 200 credits per extra mailbox every 30 days, against 4,000 credits per seat.
Where they differ
Data first, or sending first
Apollo's center is its database: 240M contacts and 30M companies, enrichment and verification paid with credits, a dialer, deals and AI agents. Sequences are one feature among many.
Instantly's center is sending: unlimited mailboxes, warm-up, rotation and Unibox. Its own database, SuperSearch, is a separate Credits plan.
Using both
One way to use both: Apollo to find and export contacts, Instantly to send. That keeps Apollo to the seats that prospect and moves the mailbox count to a tool that does not charge per mailbox.
Our Apollo MCP comparison and Instantly MCP comparison show how each server works from an assistant.
Refunds and trials
Apollo has a free plan and a one-time 14-day trial of its paid plans; it gives no refund for unused time on a downgrade. Instantly offers a 14-day trial and refunds no fees.
Which one to pick
Pick Instantly if
- You send high volume from many mailboxes
- You already have contact data and need a sending tool
- You want mailboxes unlimited without per-seat pricing
Pick Apollo if
- You need a B2B database with enrichment in the same tool
- Your team sends personal sequences from a few Google or Microsoft mailboxes each
- You want a dialer and deals next to the sequences
Where Outreach2day fits
Outreach2day is a third option: mailboxes, warm-up and a sequencer in one subscription. It is ours, so it has its own section.
Outreach2day mailboxes sync into Instantly by API key and export to Apollo as a CSV. In Apollo, each Organization seat holds 15 of them.
For email-only campaigns from lists you already have, Outreach2day all-in covers mailboxes, warm-up and the sequencer: $543 a month at 5,000 a day. Apollo's database and Instantly's lead tools have no counterpart with us.
From 1,000 mailboxes Outreach2day quotes a volume price below the per-mailbox list price of every vendor in our comparisons, including Maildoso's $0.49, with warm-up and sending in the price. Book a call and we quote your volume.
Instantly vs Apollo: questions
