What is the main difference between Mergeline and MergeMail?
These two are the closest pair on this site. Both run in Gmail as Chrome extensions2. The differences are in limits and in what each publishes. MergeMail Pro sends up to 200 emails a day; Premium and Team reach 1,500 or more by connecting your own email service1.
Mergeline Pro has no daily cap of its own. It sends up to Gmail’s limit, about 500 a day on a personal account and 2,000 on Workspace34, always through your Gmail tab, never through a separate email service.
How much do Mergeline and MergeMail cost per year?
MergeMail’s yearly prices are $12 a month for Pro ($144 a year), $49 for Premium ($588) and $19 per user for Team ($228)1. Its monthly prices were not shown on the page we read; it says yearly billing is about 25% less1.
Mergeline Pro is $12 a month or $99 a year, so it costs $45 less per year than MergeMail Pro and sends more per day.
Which one is more private?
MergeMail says it does not need access to your entire Gmail inbox and lets you choose which permissions to grant2. The exact scopes and where recipient data is stored were not published on the pages we read5.
Mergeline stores your lists, emails, results and do-not-email list in your browser’s extension storage. In its default mode it asks for no Google account permissions: it fills Gmail’s own compose window in your Gmail tab. If you choose Google sign-in instead, it asks for gmail.send, which Google classes as sensitive rather than restricted, and for gmail.readonly only if you turn on reply detection6. That data is used in your browser and never sent to a Mergeline server. The full breakdown is on our security page.
