Warmerly

Warmerly automates email warmup and checks deliverability for connected mailboxes. Its warmup sends threaded exchanges with quoted replies and natural delays, and automatically retrieves warmup messages that reach spam. InboxPulse checks SPF, DKIM, DMARC, MX, and TLS daily. Google Workspace and Microsoft 365 connect through OAuth, while other providers can use IMAP and SMTP, including Zoho and Namecheap Private Email. The service also lists LinkedIn warmup and outreach and WhatsApp messaging; LinkedIn is priced separately at $50/month per account. The free plan costs nothing and includes one email account and 100 campaign emails monthly. Starter is listed at $19 a month, and the site offers a seven-day trial. Warmerly says credentials and OAuth refresh tokens are encrypted at rest using AES-256-GCM, and requests use TLS 1.2 or higher. It says hosting and backups are in the European Union. Listed intended users include agencies, sales teams, telecom companies, lead-generation businesses, founders, SDRs, and recruiters.

Warmerly pairs email warmup with daily mailbox checks and connections to several mail providers. The free plan has a monthly campaign-email limit, and LinkedIn is priced separately.

Warmerly may suit sales teams, agencies, founders, SDRs, recruiters, and lead-generation businesses that need email warmup and mailbox monitoring. It also lists LinkedIn and WhatsApp as additional channels.

Warmerly is an email deliverability platform for senders who want to warm mailboxes and keep tabs on their configuration. It suits agencies and sales teams coordinating multiple accounts best. Its mix of warmup, daily checks and campaign capacity is useful, but the free plan’s 100 campaign emails per month is a sharp ceiling.

Overview

Warmerly combines mailbox warmup with recurring checks of email authentication and connection records. That pairing makes it more useful to teams managing several senders than to someone who only needs occasional warmup. A private warmup network and custom schedules add control, while the plan structure makes it possible to start small and expand account and campaign capacity as needs grow.

Key features

Warmup sends threaded conversations with quoted replies and natural delays, and automatically rescues warmup messages that reach spam. That rescue feature addresses a common warmup failure point; the private network and custom schedules give teams additional control over the process.

InboxPulse checks SPF, DKIM, DMARC, MX and TLS daily for connected mailboxes. Daily coverage is valuable for teams that want a regular view of mailbox configuration, rather than relying on occasional checks. Google Workspace and Microsoft 365 connect through OAuth; other providers can connect over IMAP and SMTP, including Zoho and Namecheap Private Email.

Warmerly also supports LinkedIn warmup and outreach, and WhatsApp messaging. LinkedIn costs $50/month per account separately, a material add-on for teams using more than one account. Growth includes two WhatsApp accounts and Agency includes eight.

For organizations weighing data handling, Warmerly says mailbox credentials and OAuth refresh tokens are encrypted at rest with AES-256-GCM, and requests use TLS 1.2 or higher. It says its service is hosted in the European Union, with primary databases in Hetzner facilities in Falkenstein and Helsinki and backups in the same region. The operator is Kristiyan Tsvetanov, a UK-based sole trader. Warmerly acts as a processor for customer data and controller for account information, and offers paid plans a signed Data Processing Addendum.

Pricing

The Free plan costs nothing and includes one email account, 100 campaign emails per month, 500 leads per campaign, 250 email checks per month, 50 email lookups per month and a free mailbox to warm. It is a reasonable way for one user to explore the service, but the monthly campaign-email cap rules it out for sustained campaign use. A 7-day trial is also offered.

Starter costs $19 a month, billed monthly, and raises capacity to five email accounts, five concurrent campaigns, 2,500 leads per campaign, 5,000 email checks and 1,000 lookups per month. It suits a small team stepping beyond the free account; the tradeoff is that account and campaign limits remain modest.

Growth costs $49 a month, billed monthly, and provides 25 email accounts, 25 concurrent campaigns, 25,000 leads per campaign, 25,000 checks and 10,000 lookups per month, plus two WhatsApp accounts. It is a better fit for a growing sales operation managing multiple senders, though it does not include separate client workspaces or API access.

Agency costs $179 a month, billed monthly. It includes 100 email accounts, unlimited campaigns, 100,000 leads per campaign, 150,000 checks and 100,000 lookups per month, eight WhatsApp accounts, separate client workspaces and API access. Those workspace and API provisions make it the clearest fit for agencies, while its higher price is difficult to justify for teams that do not need client separation or that much capacity. Paid plans describe email sending as unlimited and unmetered; LinkedIn remains a separate $50/month per account charge.

Platforms

Warmerly is available on Android and the web, and offers an API. Google Workspace and Microsoft 365 mailbox connections use OAuth; other mail providers can connect through IMAP and SMTP.

Who it's for

Warmerly is aimed at agencies, sales teams, telecom companies, lead-generation businesses, founders, SDRs and recruiters. It is strongest for teams coordinating multiple mailboxes or client campaigns; a solo sender with light needs may find the free tier sufficient only for limited use, while its campaign cap makes it a poor fit for regular volume.

Pros and cons

• Pros: Warmup, spam rescue and daily authentication checks are combined, giving multi-mailbox teams a broader deliverability workflow.
• Pros: Agency includes separate client workspaces and API access, useful for managing work across customers.
• Pros: OAuth for Google Workspace and Microsoft 365, plus IMAP and SMTP support, covers several mailbox connection paths.
• Cons: Free campaign sending is capped at 100 emails per month, limiting the plan to very light use.
• Cons: LinkedIn is a separate $50/month per account, so using that channel raises costs beyond the email plan.
• Cons: Agency costs $179 a month; teams without its workspaces, API access or larger quotas may not need its added capacity.

Verdict

Choose Warmerly if you need mailbox warmup and daily checks in one service, especially if you manage multiple accounts or agency clients. Its strongest reason to buy is the combination of deliverability tools with Agency workspaces and API access; look elsewhere if the free campaign quota is too small or separately priced LinkedIn would push the total cost beyond your budget.
