How Warmerly does it
Warmerly, in detail.
Mailboxes are what a Warmerly plan counts. Gmail, Outlook, Zoho, Namecheap and any SMTP and IMAP mailbox connect, hosted mailboxes are sold separately, and the count is a live one you can free by disconnecting.
01
The plan sets the number
Free covers 1 mailbox, Starter 5, Growth 25 and Agency 100. Beyond 100, Max is quoted on a call.

02
Which mailboxes connect
Warmerly connects Gmail, Outlook, Zoho, Namecheap or any custom SMTP and IMAP mailbox. Outlook.com and Microsoft 365 can also connect by a browser sign-in. Gmail and Google Workspace connect over SMTP and IMAP with a Google app password. It also has hosted mailboxes.

03
Hosted mailboxes cost extra
Hosted OneMail mailboxes are $2.99, $1.99 and $0.99 a month each on Starter, Growth and Agency, and they do not use a plan mailbox slot.
Warmerly product, checked 21 October 2026
04
Where Warmerly is behind
A plan caps mailboxes and Woodpecker does not cap email accounts on its pages. If you want many sending accounts on one low price, that favours Woodpecker.

05
Going over is refused, not charged
Connecting a mailbox beyond the plan's allowance is refused at that moment with an explanation. Nothing is charged and nothing is lost, and disconnecting a mailbox frees its slot immediately.

06
Bulk connect by API
The API has a bulk route that takes a list of accounts. Capacity is all-or-nothing: a batch that would breach the mailbox limit is refused whole, and past that gate each row succeeds or fails on its own. API access is on Agency only. We found no CSV upload for mailboxes in the app.

07
Each connected mailbox starts warming
A mailbox connected in bulk starts with warmup enabled and a status of aging. Credentials are encrypted at rest and never returned by the API.

08
Per-mailbox settings
Each mailbox has its own daily campaign limit (0 to 1000), minimum wait between sends (0 to 1440 minutes), warmup daily limit (1 to 500), timezone, from name, signature and reply-to address.

09
Hosted mailboxes sit outside the slot count
A hosted OneMail mailbox never uses a plan mailbox slot and has no cap in the pricing data, because it is billed per unit. On the Agency plan one costs $0.99 a month.

How Woodpecker does it
Woodpecker, in detail.
Email accounts are listed as unlimited and free in the base price, with paid add-ons for addresses and domains bought through Woodpecker. The help centre shows 25 article titles on connecting, bulk adding and troubleshooting.
01
Unlimited email accounts
The base price lists 'Email accounts: Unlimited', with $20 struck through and shown as FREE. Inbox rotation sends from several accounts, and the features page says connected accounts are free to use because the price is not per email slot.

Connection guides
The help centre lists guides for Gmail and Google Workspace, Microsoft and Outlook, Zoho, OVH, GoDaddy, IONOS, DreamHost, a custom account, Amazon SES, SendGrid and Mailgun, and a guide on bulk adding mailboxes. Titles only; we did not read the articles.

Addresses and domains as add-ons
Add-ons list email addresses at $6 each (Google or Microsoft, 0 to 200) or $4 each (Maildoso, Mailforge, Infraforge or Azure, 0 to 200), new domains at about $1 each billed annually, and domain transfer at $1 each.

CSV upload and its limits
The features page says email accounts can be uploaded in batches of up to 200 from a CSV file. The help article adds that one file must be below 200 KB, that a campaign can take up to 1,000 mailboxes added from a CSV, and that you can start a new batch while others process.

Any provider through SMTP
The features page says you can connect an email from any provider to Woodpecker through SMTP, naming Google, Office 365, Zoho and SendGrid.
woodpecker.co/features · read 22 October 2026
06
CSV fields for bulk adding
The bulk CSV needs SMTP email, login, password, server, port and from name, plus IMAP email, password, server and port. Signature, BCC address, tracking domains, sending frequency and daily limit are optional. Results show under an Added tab, and failures list under Pending with the connection problem for each.

Bulk edits to settings
From the accounts table you can tick several mailboxes and change the campaign daily limit, the warm-up daily limit and the reply percentage together, or set them as defaults for new mailboxes.

Provider limits guide
A help article lists provider limits: free Gmail 100 messages by SMTP and 20 an hour, G Suite 2,000 a day (500 on trial), Office365 10,000 a day and 30 a minute, GoDaddy Workspace 500 a day. It also says not to send more than 100 messages a day from a mailbox, and that Woodpecker applies the limit it suggests when you set one up.

What Woodpecker does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Any cap on connected accounts, or a fair use rule for them
- Whether warm-up, sending limits or deliverability checks differ by provider
- How many accounts a single campaign can rotate through beyond the 1,000 from a CSV
- Whether unlimited accounts are subject to a fair use rule in the terms of service, which we did not read
- The permitted values for daily limits in the bulk CSV
Where the sources disagree
We report each version rather than pick one.
- The Warmerly sign-in wording on Google changed on 15 September 2026: new Gmail and Google Workspace mailboxes connect with an app password, not Google sign-in. Older mailboxes connected by Google sign-in keep working.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Many accounts, one price
If you rotate through many email accounts and want no per-account line, Woodpecker's unlimited accounts are an advantage. Warmerly's plans are priced for a set number.
Hosted addresses
Both tools sell hosted addresses. Warmerly's cost less on a higher plan; Woodpecker's are $4 to $6 whatever you pick. We did not compare the products behind them.
Moving 30 mailboxes in
On Woodpecker, 30 accounts fit in one CSV of up to 200 and the connection itself is free of charge on the pricing page. On Warmerly, 30 mailboxes is above Growth's 25, so Agency at $179 a month for 100 is the fit. Connecting is one by one in the app, or by API on Agency.
A team adding mailboxes together
Woodpecker's Pending tab shows what every user has requested, which helps a team that adds accounts in parallel. We did not find an equivalent view described for Warmerly.
Setting a sensible daily limit
Warmerly defaults a mailbox to 30 campaign sends a day and lets you set 0 to 1000. Woodpecker's help article advises staying at or under 100 a day. Neither number is a promise about your results; both depend on the provider and the age of the mailbox.
Choosing between hosted and your own
Ten hosted mailboxes on Warmerly's Growth plan would be 10 times $1.99, which is $19.90 a month, and on Agency 10 times $0.99, which is $9.90. On Woodpecker, ten addresses are $60 a month for Google or Microsoft, or $40 a month for Maildoso, Mailforge, Infraforge or Azure. We did not compare the products behind these prices.
