Short answer

As of October 2026, Instantly sells three kinds of sending accounts inside its app: done-for-you Google accounts at $5 per account per month, pre-warmed Google accounts at $10, and AirMail accounts on its own servers at $4, each plus $15 per domain per year. The alternative is to buy mailboxes elsewhere and connect them to Instantly. Winnr mailboxes export straight into Instantly and cost $1.38 each at 50 ($69/month) and $0.95 each at 200 ($189/month). Choose Instantly's own accounts if you want real Google seats, no import step and everything on one Instantly bill. Choose Winnr if you want the lower price, the option to keep domains at your own registrar, and mailboxes you can move to another sequencer.

Instantly facts below come from instantly.ai and Instantly's help center, read on October 6, 2026. Winnr's prices are on the public pricing page. Instantly is one of the sequencers Winnr exports to.

What Instantly sells as of October 2026

All three are bought from the Email Accounts page inside Instantly, and you need an Instantly plan to send from them.

Rules that apply across these purchases, per Instantly's help center:

Using Winnr mailboxes in Instantly

Winnr sells SMTP/IMAP mailboxes on its own sending infrastructure, with domains, DNS, warming and a universal inbox in one dashboard. In Winnr you open Email Users, choose Export, pick the Instantly format and download a CSV. In Instantly you add accounts with the any-provider (SMTP/IMAP) option and upload the file with its bulk CSV import. The file already sets Instantly's daily limit to 15 and leaves Instantly's warmup off, so a mailbox Winnr warms is not warmed twice. Step-by-step: connect Winnr mailboxes to Instantly, or see cold email inboxes for Instantly for the overview.

Instantly's pricing says every Outreach plan includes unlimited email accounts and warmup, so connecting Winnr mailboxes adds nothing to your Instantly bill. You pay Instantly for the plan either way.

Cost at 50, 200 and 1,000 mailboxes

Monthly cost of the mailboxes only. Your Instantly plan costs the same in every column, so it is left out. Winnr is the plan price plus $1 for each mailbox above it; Instantly's accounts are a flat rate, so mailboxes × price (200 × $4 = $800).

MailboxesWinnrAirMailDFY GooglePre-warmed Google
50$69 (Startup)$200$250$500
200$189 (Enterprise)$800$1,000$2,000
1,000$989 ($189 + 800 × $1)$4,000$5,000$10,000

Domains. At 5 mailboxes per domain all four options need 10, 40 and 200 domains. On Instantly that is $150, $600 and $3,000 a year at $15 each. Through Winnr it is a one-time $130, $455 (Enterprise includes 5 free domain purchases) and $2,535 at about $13 per .com, or nothing if you connect domains you already own.

Warming. Pre-warmed accounts arrive warmed and AirMail includes Instantly's warmup. Winnr's warming add-on is $0.60 per mailbox per month ($30 at 50), or you can leave it off and use Instantly's warmup, which every Instantly plan includes. Winnr's own pre-warmed mailboxes are $3 per address per month against $10 for Instantly's pre-warmed Google accounts.

Monthly cost per 1,000 daily cold sends

A fairer number than price per mailbox is what you pay each month for every 1,000 cold emails you can send per day: monthly price per mailbox ÷ cold emails per mailbox per day × 1,000. We use each option's own guidance where Instantly publishes one, and Winnr's default of 15 a day (its range is 10 to 20 cold per mailbox).

OptionPer mailbox / monthCold emails / mailbox / dayMonthly cost per 1,000 daily cold sends
Winnr, 50 mailboxes$1.3815$92.00
Winnr, 200 mailboxes$0.9515$63.00
Winnr, 1,000 mailboxes$0.9915$65.93
Instantly AirMail$4.0020 (its strict maximum)$200.00
Instantly DFY Google$5.0015 (no published figure; same as Winnr)$333.33
Instantly pre-warmed Google$10.0025 (top of its 20 to 25 cap)$400.00
Worked example: 3,000 cold emails a day

Winnr: 200 mailboxes at 15 a day, $189 a month on Enterprise, 40 domains. AirMail: 150 accounts at 20 a day, $600 a month, 30 domains at $15 a year. DFY Google: 200 accounts at 15 a day, $1,000 a month, 40 domains at $15 a year. Your Instantly plan is the same in all three.

When Instantly's own accounts are the better fit

When Winnr is the better fit

You do not have to pick one. Instantly itself recommends mixing infrastructure types (its AirMail article suggests starting with half AirMail and half Google inboxes), and Winnr mailboxes sit in the same Instantly workspace as any Google accounts you buy there. For the wider market, see Winnr alternatives and the comparisons with Smartlead SmartSenders, InboxKit and Maildoso.

Frequently asked questions

Can I use Winnr mailboxes in Instantly?

Yes. In Winnr, export your mailboxes in the Instantly format and download the CSV, then upload it in Instantly with the bulk import for any SMTP/IMAP provider. The file sets Instantly's daily limit to 15 and leaves Instantly's warmup off. Instantly's Outreach plans include unlimited email accounts, so connecting them does not add to your Instantly bill.

How much do Instantly's done-for-you email accounts cost?

As of October 2026: $5 per account per month for done-for-you Google accounts, $10 for pre-warmed Google accounts and $4 for AirMail accounts, plus $15 per domain per year, with up to 5 accounts per domain. You also need an Instantly plan to send from them.

What is Instantly AirMail?

AirMail is Instantly's own SMTP sending infrastructure, announced in May 2026 and priced at $4 per inbox per month. The inboxes run on Instantly's servers and IPs and are used only inside Instantly. Its help center sets a strict maximum of 20 emails per inbox per day and says mail to personal providers such as gmail.com is dropped.

Is Winnr cheaper than Instantly's email accounts?

Yes, per mailbox and per email sent. 50 Winnr mailboxes cost $69 a month ($1.38 each) and 200 cost $189 ($0.95 each), against $4 per account for AirMail and $5 for DFY Google accounts. At each option's own daily guidance, Winnr comes to $63 to $92 per 1,000 daily cold sends against $200 for AirMail.

Can I move Instantly DFY accounts to another sequencer?

Instantly's help center says its done-for-you and pre-warmed Google accounts are configured exclusively for use within Instantly, and that Instantly retains domain ownership and administrator access and cannot transfer them. AirMail has no login outside Instantly. Winnr mailboxes can be exported to Instantly and 20+ other sequencers.

Do I still need an Instantly plan if I use Winnr mailboxes?

Yes. Instantly runs the campaigns either way, so you pay for an Instantly Outreach plan (from $47 a month on Growth as of October 2026) whether your accounts come from Instantly or from Winnr. Winnr covers the mailboxes, domains and warming.
