Mailmeteor

Mailmeteor is a mail-merge and email campaign tool for Gmail, Outlook, spreadsheets, and documents. It best suits people and teams who want to personalize outreach and keep campaign replies manageable. Its campaign controls span scheduling, tracking, and follow-ups, but the right paid tier depends on how many emails and senders you need.

Overview

Mailmeteor brings personalized sending and reply management into workflows built around Gmail, Outlook, Excel, Google Sheets, or Google Docs. That breadth makes it a practical fit for freelancers and teams whose contact data already lives in those tools. The free plan is a useful way to start, but its 500-email monthly allowance is modest for ongoing outreach.

Key features

Users can build campaigns with templates, attachments, scheduling, audience segmentation, unsubscribe management, and conditional follow-ups. Open, link, and reply tracking help monitor engagement, while activity alerts offer another way to keep tabs on campaigns. These features make Mailmeteor more than a basic mail merge, though high-volume senders will need to plan around both daily and monthly caps.

The AI assistant can sort email, draft replies in the user's tone, and rewrite, improve, or shorten messages. It is available only for Gmail, which limits its appeal to Outlook users. Zapier connects Mailmeteor to an ecosystem of 5,000+ apps, and Google Sheets automations support spreadsheet-based workflows. Salesforce and HubSpot logging works through each CRM's unique BCC address rather than a native CRM integration.

Mailmeteor says it requests only the permissions needed to send email, not access to read, modify, or delete email data. It also says customer data stays in the Google Spreadsheet by design and that it complies with French data protection laws and GDPR. TAC Security audited its infrastructure and source code in November 2025 for CASA Tier 3 requirements and Google API usage.

Pricing

Mailmeteor has a free Hobby plan and three paid tiers, with paid prices billed per user per month. There is no free trial, so the free plan is the way to assess the product before paying.

• Hobby: free. It allows 500 emails/month and includes templates, tracking, scheduling, attachments, and Gmail, Sheets, and Excel support. It suits occasional or small campaigns, but has far less capacity than the paid tiers.
• Starter: $5.99 a month (billed per user / month). It raises capacity to 5,000 emails/month and 250 emails/day, with one sender, 50,000 contacts, Autopilot, email verification, and Zapier. This is the entry point for regular single-sender outreach, but it lacks the follow-ups, Sheets automations, and AI assistant included at Premium.
• Premium: $17.99 a month (billed per user / month). It includes 30,000 emails/month, 1,000 emails/day, five senders, and 500,000 contacts, plus follow-ups, Sheets automations, the AI email assistant, and warmup. It is the stronger fit for users running multiple campaigns or needing those tools; Gmail is still required for the assistant.
• Professional: $35.99 a month (billed per user / month). It allows 60,000 emails/month and 2,000 emails/day, with 10 senders, 1,000,000 contacts, inbox rotation, dedicated onboarding, and priority support. The extra capacity and support are aimed at larger outreach operations, rather than users who can stay within Premium's limits.

Hobby's free-plan cap is presented as 500 emails per month; the FAQ also describes free use up to 50 emails per day. Paid-plan quotas are constrained by both daily and monthly limits, so the monthly total alone does not determine how quickly a campaign can be sent.

Platforms

Mailmeteor is available as a web app and extension. Its mail merge works with Gmail, Outlook, Excel, Google Sheets, and Google Docs, but the AI assistant is Gmail-only.

Who it's for

Sales teams, marketers, recruiters, founders, customer support teams, and freelancers are among the audiences Mailmeteor describes. It makes the most sense for people who want personalized campaigns alongside scheduling, tracking, and reply management. Outlook users can still use campaign tools, but should look elsewhere if the Gmail-only assistant is essential.

Pros and cons

• Pro: Mail merge works across email, spreadsheet, and document workflows, so users need not keep campaign work in Gmail alone.
• Pro: Scheduling, tracking, segmentation, unsubscribe management, and conditional follow-ups cover key campaign tasks in one product.
• Pro: The free plan includes tracking, scheduling, and attachments, making it useful for low-volume evaluation without a trial.
• Con: Hobby is capped at 500 emails/month, making it a poor fit for sustained outreach.
• Con: The AI assistant is limited to Gmail, and CRM logging relies on BCC addresses rather than native integrations.
• Con: Paid plans have daily as well as monthly quotas, and higher capacity requires a higher per-user price.

Alternatives

Choose Mixmax if its free tier's 20 tracked emails/month and up to 50 sequence recipients/month better match your needs. Yesware is another freemium option, with basic open and attachment tracking, 10 campaign recipients/month, and a meeting scheduler on its free plan. Choose Apollo if its free plan's 900 credits per seat per year, two sequences, API access, and one intent topic fit your workflow. Hunter offers a free plan with 50 monthly credits, basic Discover filters, one connected email account, and 500 recipients per sequence.

Outplay offers a free-forever plan with one user, two mailboxes, and 2,000 active prospects/month. Senders.ai has a freemium model. Sequence-R offers an Individual plan at $16 a month, with three connected inboxes, inbox rotation, three active campaigns, 3,000 emails/month, and 1,000 active records.

Verdict

Mailmeteor is a strong choice for individuals and teams who want mail merge, campaign management, and reply tracking in workflows spanning Gmail, Outlook, and spreadsheets. Its free plan supports small-scale use, while Premium and Professional add the capacity and follow-up tools for heavier campaigns. Look elsewhere if you need a Gmail-independent AI assistant, or if Hobby's modest quota is not enough and the paid per-user tiers do not fit your budget.
