A Gmail Extension

✉️ Send Mass Mail + HTML Inserter for Gmail — mail merge, follow-ups and reply tracking inside Gmail COMPOSE campaigns right inside Gmail Click “Compose”, write your email as usual, add recipients from Google Sheets, a pasted list or a CSV — and press “Send Mass” next to Gmail’s Send. Everyone gets an individual email from your own address. No new app to learn, no copying your contacts anywhere. NEW: follow-ups if no reply Add up to three follow-up steps and MailBrother sends them in the same thread to everyone who has not replied. The sequence stops on a reply, an unsubscribe, a bounce or a click. AI drafts the follow-up text from your first email. NEW: real replies, sorted for you Replies to your campaigns are detected and sorted as interested, question, not now, not interested or “please stop”. Labels appear in Gmail, and one click creates an AI-drafted answer as a Gmail draft you only have to send. CHECK before you send A pre-flight window shows a checklist (missing subject, empty tags, link shorteners, spam signals), a spam score, the email personalized for your first recipients, and a “Send test to me” button. Sixty seconds after Send Mass you can still cancel. PERSONALIZE at scale Merge any column from Google Sheets or CSV with {FirstName}, {Company} and fallbacks like {FirstName|there}; conditional blocks {if Plan=Pro}…{/if}; “Enrich recipients” adds the company name, description and a personal opening line from the email domain. MEASURE what matters Opens, clicks, bounces, unsubscribes and real replies per recipient; clicked links, mail clients and countries; the best hour to send from your own history; anonymous MailBrother averages for comparison; a weekly report in your inbox; export to PDF, CSV or TXT; results written back into your Google Sheet. STAY OUT OF SPAM One-click unsubscribe headers (Gmail shows its own Unsubscribe button), SPF/DKIM/DMARC check with a fix guide, suppression list that skips unsubscribed, bounced and “stop” addresses in every campaign, address verification, auto-pause on bounce spikes or complaints, gradual warm-up for new accounts, a plain-text version added to HTML emails.
