Mailmeteor

Mailmeteor's AI assistant sorts Gmail conversations, prepares reply drafts in the sender's voice and rewrites selected text, with conversation history supplying the context and each account keeping its own settings. AI is optional and starts only once the user enables it. Smart labels appear in Gmail's mobile apps, while writing help works through the desktop Chrome extension.

The underlying mail merge product sends authored templates from Sheets, Docs, Excel or the dashboard, with follow ups, scheduling and tracking that need no AI, so removing the assistant leaves a complete campaign tool.

The Gmail assistant prepares drafts for a person to review, while campaign sequences send automatically after launch. Pausing a campaign stops its emails and its follow ups; on resumption, future follow ups continue, but steps whose deadlines passed during the pause are canceled rather than sent late. Senders can also remove recipients or end a campaign. Autopilot controls sending days, hours, daily caps and the gap between emails.

Sheet automations can launch sends from a form response, an edited sheet or a recurring schedule without a person pressing send. AI categorization can be switched off, and wrong labels can be moved or removed by hand.

OpenAI is named as an AI service provider in the United States, though specific model versions are not, and Mailmeteor adds no default notice telling recipients that a message was AI drafted. The assistant uses email threads to prepare replies, writes drafts in the sender's own voice and sorts mail into labels such as to respond, FYI and agenda, which also appear in Gmail's mobile apps.

Users choose which categories to enable and can change a draft's tone, shorten it or correct its grammar. Auto labels and auto drafts arrive with Premium, and a free AI email writer is offered separately on the website.

Mailmeteor's evidence is adoption rather than measured outcomes. It says six million users trust its products, cites a 4.9 out of 5 rating across more than 10,000 reviews, and notes that Google recommended its Sheets mail merge add on as a market leading application in 2022 and 2023. Customer feedback describes faster personalized sending, useful tracking and straightforward spreadsheet exports, but no testimonial ties revenue or meetings to a named business and period. The dashboard tracks sends, opens, clicks, replies and unsubscribes for each customer's own campaigns.

An unsubscribe adds the address to a list that blocks later campaigns and follow ups, and existing suppression lists can be imported. Inserting an unsubscribe link also turns on the mailbox provider's one click unsubscribe, and the composer offers an editable link and a dedicated template variable. Resubscribing someone is a manual action. BounceShield flags invalid recipients as failed ahead of each send. Mailmeteor places lawful contact and consent collection on the customer rather than collecting permission for imported audiences, and its DPA makes the customer the controller of every mailing list.

A public DPA makes Mailmeteor the processor and the customer the controller for mailing lists, and the security center links it alongside a risk management policy. Recipients can request access, correction or deletion, and Mailmeteor maintains a subprocessor list. Processing reaches the United States through Google Cloud storage and OpenAI, and the transfer section leaves the operative safeguard unclear despite references to EU clauses elsewhere. The privacy policy limits list processing to running the service and prohibits selling or renting those records. Email events are kept 90 days and recipient merge data 180 days.

Most campaign information comes from the customer's own contact lists, spreadsheet fields and message content, whether in Google Sheets, Excel, Docs or the dashboard. The separate Email Finder takes a person's name and company and returns a likely professional address after verification, and it withholds a result when it cannot find a verified one. Individual lookups are free within fair use limits. Mailmeteor does not explain the source inventory or licensing rights behind Email Finder results. Starter adds email verification for imported lists before they are sent.

Mailmeteor supports Gmail, Outlook and SMTP connections and applies mailbox quotas to its sends, and it states Google's own ceilings: up to 2,000 emails a day from a Google Workspace account and 500 from a personal Gmail address. Professional also markets inbox rotation to spread volume and reduce the chance of hitting sending limits or spam filters. Rotation assigns a sender before delivery and keeps it for the life of the campaign, including every follow up to the same recipient. The Sheets add on uses Google's authorization flow and asks only for the permissions needed to send.

AI features are opt in, and Mailmeteor prohibits its AI providers from training models on customer data; switching a feature off stops further data transfers. Inference inputs are deleted after processing or at the end of the provider's safety retention window, for which no duration is given. Other product data has set schedules: email events are kept 90 days, and recipient merge data and follow up settings 180 days. The Sheets add on requests only the permissions needed to send, while the Gmail assistant reads conversation history, so enabling it widens what Mailmeteor processes.

AI replies are drafts in the sender's own mailbox, built from the conversation's history and the sender's preferred tone, and the sender can change the wording before sending. Mailmeteor takes no public Article 50 position and adds no default label to AI authored outreach. Campaign identity stays tied to a connected sender, and inbox rotation keeps later messages in the same recipient's thread from the address first assigned, so the recipient always hears from one person. A custom tracking domain on Premium keeps tracked links on the sender's own domain.

Google Sheets, Google Docs, Excel, Gmail and the dashboard give different campaign entry points, and Outlook and SMTP accounts can send alongside Gmail. CRM logging uses each receiving system's BCC address, including Salesforce, HubSpot and Copper, which records email activity rather than synchronizing a contact database or opportunity workflow. Zapier connects other applications from Starter upward. Spreadsheet automations can start from a form response, an edited sheet or a recurring schedule. Pipelines arrive with Professional for tracking replies through stages inside Mailmeteor itself.

Mailmeteor is a hosted service reached through a web dashboard, a Gmail extension and add ons for Google Sheets, Google Docs and Excel. Its subprocessor list places Google Cloud storage and OpenAI processing in the United States, Scaleway computing in France and IPAPI.is in Germany, and customers get no region selection. A connected Google or Microsoft mailbox supplies the sender, while the dashboard holds contacts, campaign settings and activity history for the account. Prices can be shown in USD, EUR or INR.

TAC Security audited Mailmeteor's infrastructure and source code in November 2025 for CASA Tier 3, Google's assessment for apps using its APIs, and the letter of assessment is downloadable from the security center, with an earlier Tier 3 letter from December 2024. SOC 2 is still in preparation. The same page offers a security whitepaper, a risk management policy, a vulnerability disclosure program and the HECVAT questionnaire (version 3) for education buyers. The whitepaper covers encryption in transit and at rest, logical customer separation and restricted, logged staff access with multifactor authentication.

Starter costs $5.99 per user a month, Premium $17.99 and Professional $35.99; annual billing, which works out to three months free, totals $53.99, $161.99 and $323.99. The purchase table gives monthly allowances of 5,000, 30,000 and 60,000 emails, with a free Hobby plan at 500.

Starter adds verification, shared templates, reply detection and Zapier; Premium adds follow ups, sheet automations, extra senders, the full AI assistant, warmup and a custom tracking domain; Professional adds inbox rotation, pipelines and priority support. Starter's quota guide still carries a conflicting 7,500 figure, and paid tiers have daily ceilings of 250, 1,000 and 2,000 emails.

Contacts export to CSV, either as the full collection or an individual list, and Sheets based campaigns keep their source data in the customer's own spreadsheet. Customers can cancel from billing settings or through support, and paid access continues through the purchased period. The terms offer a conditional refund within 30 days, with accounts that have run campaigns reviewed before approval. Account termination ends access to stored data, and email events are kept for 90 days and merge data for 180 days in the meantime. Sent messages remain in the connected mailbox.

Autopilot sets sending days, hours, daily caps and intervals between messages, and quotas are checked before each email, though no numeric reputation threshold stops an entire account automatically. BounceShield checks addresses for typographical and technical problems before sending and marks invalid recipients as failed. Consumer mailboxes can run below a paid plan's ceiling, and Mailmeteor states Google's own daily limits.

Premium adds email warmup and a custom tracking domain, and the Deliverability Hub gathers sending guidance from Starter upward. Professional's rotation keeps each recipient with one sender for the whole sequence.

The product serves salespeople, marketers, founders and recruiters who run outreach from their existing inboxes and spreadsheets, and testimonials give limited detail on organization size. It also has an education program, with a HECVAT questionnaire for institutions, and team license administration. Support is offered in English, Spanish and French, and prices display in several currencies.

B2B campaign templates cover prospecting, event follow ups and customer nurturing alongside routine office communication. Professional is pitched at teams sending at scale, with team analytics on the way.
