Reply.io vs Instantly pricing and which is better for cold email

The short answer

Instantly is the better buy when outbound is cold email at volume, and Reply.io is the better buy when reps also work LinkedIn and the phone. Instantly Growth costs $47 a month, or $37.60 billed annually, for unlimited mailboxes and warm-up, 1,000 uploaded contacts and 5,000 emails a month; Hypergrowth is $97 ($77.60 annually) for 125,000 emails. Reply.io Email Volume starts at $59 a month for 1,000 active contacts, and Multichannel starts at $99 per user with one LinkedIn account and calling included per user. Neither writes a researched email for each prospect. AutoMail does, flat per workspace from $24 a month annual.

Quick verdict

Who each tool is for

Both Reply.io and Instantly are capable. Here is the shortest honest way to choose, with where AutoMail fits.

Pick Instantly

Outbound is cold email and volume is the job. Unlimited mailboxes and warm-up are in every plan, Hypergrowth sends 125,000 emails a month for $97, or $77.60 billed annually, and nobody pays per seat for the mailboxes they add.

Pick Reply.io

Each rep works email, LinkedIn and the phone in the same sequence. Multichannel starts at $99 per user a month with five mailboxes, one LinkedIn account and calling included per user, and Jason the AI SDR is available from $500 a month.

Pick AutoMail

The email itself is the problem. The AI researches each company, writes the opener and every follow-up for that prospect, sends from warmed and rotated inboxes, pauses on reply and routes interested prospects to your booking link. Flat per workspace from $24 a month annual, unlimited seats.

Reply.io and Instantly show up on the same shortlist because both send cold email sequences from several mailboxes, but they are built for different buyers. Instantly is an email sending engine: unlimited connected inboxes, unlimited warm-up and plan tiers set by how many emails you send and how many contacts you upload. Reply.io is a sales engagement platform: email, LinkedIn, calls, SMS and an AI SDR called Jason in one sequence builder, with prices that climb by active contacts on the email plan and by seat on the multichannel plan.

We read both pricing pages in October 2026. Instantly lists Growth at $47, Hypergrowth at $97 and Light Speed at $358 a month, or $37.60, $77.60 and $286.30 a month billed annually. Its B2B lead database is a separate credits plan from $47 a month for 1,500 credits, and bundles that combine sending, credits and its AI agents run $94, $194 and $555 a month. Reply.io lists Email Volume from $59, Multichannel from $99 per user, Agency from $166 and AI SDR from $500, with LinkedIn at $69 a month per account and Calls and SMS at $29 per user when the plan does not include them.

The number the plan cards leave out is infrastructure. Instantly lets you connect as many mailboxes as you like on every plan, but you still buy the domains and inboxes yourself. Reply.io now sells them inside the app: a new domain from $6 a year plus $5 per mailbox a month, a pre-warmed domain from $25 a year plus $15 per mailbox a month, and extra mailboxes on Multichannel at $29 each a month. Neither product researches a prospect and writes the email for you, which is where most reply rate is won or lost.

The third option

Where AutoMail fits between them

The AI writes the sequence

Both tools above leave the copy to you. AutoMail researches each prospect and writes a genuine 1:1 opener and follow-ups, so relevance, not just volume, drives the reply rate.

Deliverability built in

Inbox rotation, gradual warm-up and a spam-score check on every send keep personalized copy in the primary inbox, built for the 2026 Google and Microsoft sender rules.

Replies become meetings

When a prospect answers, the sequence pauses, intent is classified, and meeting-ready replies route to your booking link and CRM. Flat per workspace, unlimited seats, no credits.

One honest caveat: AutoMail has no built-in lead database, so bring or sync your own verified list. If prospecting data is what you need most, keep a data tool for that and run the outreach here.

Good questions

Reply.io vs Instantly, answered

Instantly is better for cold email at volume: unlimited mailboxes and warm-up on every plan, from $47 a month or $37.60 annually. Reply.io is better when reps also run LinkedIn and calls, since Multichannel at $99 per user includes one LinkedIn account and calling per user. For email only, Instantly costs less per email sent.

For email-only outbound, usually yes. Instantly Hypergrowth sends 125,000 emails a month for $97, or $77.60 billed annually, with unlimited mailboxes. Reply.io Email Volume starts at $59 a month but is priced by active contacts, so the bill grows with your list. Once LinkedIn or calls are needed, Instantly has no equivalent to compare.

No. Instantly sends email only, with no LinkedIn, call or SMS steps. Reply.io adds LinkedIn at $69 a month per account on its email plans and includes one LinkedIn account per user on Multichannel. Teams on Instantly usually pair it with a separate LinkedIn tool, which adds a second subscription and a second inbox.

Reply.io lists Email Volume from $59 a month for 1,000 active contacts, Multichannel from $99 per user, Agency from $166 and the AI SDR plan from $500. LinkedIn is $69 a month per account and Calls and SMS $29 per user where the plan does not include them. Extra Multichannel mailboxes cost $29 each a month.

Instantly Outreach plans are Growth at $47 a month, Hypergrowth at $97 and Light Speed at $358, or $37.60, $77.60 and $286.30 a month on annual billing. Lead data is a separate credits plan from $47 a month for 1,500 credits, and bundles combining both run $94, $194 and $555 a month.

Instantly includes unlimited email accounts and warm-up on every Outreach plan. Reply.io Email Volume also lists unlimited mailboxes, subject to its fair use policy, while Multichannel includes five per user and charges $29 a month for each extra one. Both still need you to own the domains, though Reply.io now sells domains and mailboxes in the app.

Deliverability depends mostly on your domains, authentication, list quality and volume per mailbox, not the brand of sender. Instantly makes the safe setup cheaper because unlimited mailboxes and warm-up are in every plan. Reply.io offers warm-up through Mailtoaster.ai and sells pre-warmed mailboxes from $15 a month each. Keep each mailbox around 30 to 50 cold emails a day either way.

Instantly is the common agency choice for email, since one workspace connects unlimited client mailboxes and Light Speed sends 500,000 emails a month. Reply.io has a dedicated Agency plan from $166 a month with client workspaces and adds LinkedIn when clients want it. Agencies selling email results should compare cost per client workspace, not per seat.

Partly. Instantly has an AI email writer agent that runs on credits, and Reply.io sells Jason, an AI SDR, from $500 a month. Both still expect you to set the angle and check the copy. AutoMail researches each company, writes the opener and every follow-up for that prospect, and is priced flat per workspace from $24 a month annual.

If the gap is the copy rather than the sending, AutoMail is the alternative: it writes a researched 1:1 sequence for each prospect, sends from warmed and rotated inboxes, stops on reply and routes interested prospects to your booking link. It costs $49 a month or $24 annual on Starter, with unlimited seats and no credits.
