Boomerang and Recurrr can both send the same email again and again on a schedule, but they are different kinds of product. Boomerang is a browser extension that adds a set of inbox features to Gmail or Outlook: send later, follow-up reminders, read receipts, inbox pause, meeting scheduling, and recurring messages. Recurrr is a tool that sends recurring emails from your own Gmail or Outlook account, on any schedule, and that is all it does.
The short answer: if recurring emails are the only thing you need, Recurrr is simpler and costs less ($9/month or $45/year, against $14.98/month billed annually for the Boomerang plan that includes recurring messages). If you would also use Boomerang's other features, such as response tracking or inbox pause, Boomerang gives you more for the money. Full disclosure: Recurrr is our product, so we have tried to stick to facts you can check on each vendor's site.

How recurring emails work in Boomerang
Boomerang has offered recurring messages in Gmail for well over a decade, and the feature is solid. Once the extension is installed, a "Send Later" button appears in the Gmail compose window. To make an email repeat:
- Compose the email in Gmail as usual.
- Click "Send Later", then "Schedule recurring message" at the bottom of the menu.
- Pick the start date and time, choose whether it repeats daily, weekly, monthly or yearly, and adjust the frequency.
- Choose when the series ends: after a number of messages, on a date, or never.
- Click "Schedule". The message is kept under a "Boomerang-Outbox" label and sends on schedule, even when your computer is off.
What is good about it: you never leave Gmail, and recurring messages sit next to features many people want anyway. Boomerang's follow-up reminders ("bring this back to my inbox if nobody replies") are something Recurrr does not do at all.
What to know before you pay for it:
- Recurring messages are not on the free or Personal plans. They start at Pro, which is $14.98/month billed annually for Gmail. That works out to about $180 a year.
- Gmail and Outlook are separate products. Boomerang for Outlook has its own plans, and recurring messages are again on Pro ($14.99/month billed annually). If you send from both, you are looking at two products.
- It is an extension. On desktop you need Chrome or Firefox with the extension installed to create and edit recurring messages, and the extension works inside your mailbox.
- The schedule is a form. Daily, weekly, monthly and yearly patterns are covered. There is no single place to type a rule like "the last working day of each quarter".
How recurring emails work in Recurrr
Recurrr is a web app, and recurring emails are the only thing it does. There is nothing to install:
- Go to recurrr.com and sign up with "Continue with Google" or "Continue with Microsoft". That connects your Gmail or Outlook address: no extension, no app password. Other providers (Fastmail, Yahoo, Zoho and so on) connect over SMTP.
- Click "Compose" and write the email once: recipients, subject and message.
- Type when it should go out, in plain English: "every Monday at 9am", "every two weeks on Tuesday", "last Friday of the month". Recurrr shows how it understood the schedule before you save.
- Save it. Recurrr sends the email from your own address on every occurrence, and a copy lands in your Sent folder. You can edit, pause or stop it from the calendar view.
What is good about it: the setup takes a couple of minutes, it only asks for permission to send (it cannot read your inbox), the same account covers Gmail, Outlook and SMTP addresses, and a calendar shows every email that is going to go out.
What to know before you pay for it:
- It does one thing. No email tracking, no follow-up reminders, no inbox pause, no meeting scheduling.
- There is no free-forever plan. You get a 14-day free trial, then it is $9/month or $45/year.
- It lives outside your inbox. You write recurring emails at recurrr.com, not in the Gmail compose window. Some people prefer that; some would rather stay in Gmail.
- It is built for person-to-person email. The Standard plan covers 30 recurring emails, 3 sending addresses and up to 30 recipients per email. It is not a newsletter tool.
- No mobile app. The site works on a phone, but there is nothing in the app stores.
What each one costs over a year
If recurring emails are the reason you are buying:
| Per year | |
|---|---|
| Boomerang for Gmail, Pro | $179.76 ($14.98/month, billed annually) |
| Boomerang for Outlook, Pro | $179.88 ($14.99/month, billed annually) |
| Recurrr, paid yearly | $45 |
| Recurrr, paid monthly | $108 ($9/month) |
Boomerang's price buys a lot more than recurring messages, so the comparison is only fair if you would not use the rest. If you would, Boomerang Pro replaces several small tools at once.
Which one should you choose?
Choose Boomerang if:
- you want follow-up reminders, response tracking, read receipts or inbox pause, and recurring messages are a bonus;
- you want to schedule everything from inside the Gmail compose window;
- you want native iPhone and Android apps.
Choose Recurrr if:
- recurring emails are the only thing you are missing: a weekly status request, a monthly invoice or rent reminder, a quarterly check-in;
- you would rather not install an extension or give a tool access to your inbox;
- you send from more than one provider, for example a Gmail address and an Outlook address;
- your schedules are awkward to fit into a form, such as "the first Monday of every month" or "every other Thursday".
Plenty of people would be well served by either. We used Boomerang ourselves for a while, and only moved on when we noticed recurring messages were the one feature we opened it for.
Other Boomerang alternatives for recurring emails
If neither fits, these are the other common ways to send a recurring email:
- Right Inbox and GMass: Gmail extensions in the same family as Boomerang. Right Inbox is a general inbox toolbox; GMass is a mass-email tool whose recurring option is limited to every few weeks or months.
- Google Apps Script: free and as flexible as you can code, but you write and maintain the script yourself.
- Zapier or Make: a schedule trigger followed by a "send email" step. No code, more setup, and priced by usage.
- Gmail and Outlook on their own: "Schedule send" sends one email once. Neither has a repeat option.
We compare all of them, with pros and cons, in our list of the top tools to send recurring emails.
Frequently asked questions
Does Boomerang's free plan include recurring emails?
No. Recurring Messages are part of Boomerang's Pro and Premium plans for Gmail, and of the Pro plan for Outlook. The free Basic plan and the Personal plan do not include them. New accounts get a 30-day trial of Pro, so you can try the feature before paying.
Is Recurrr a Boomerang alternative?
For recurring emails, yes. Recurrr is a tool that sends recurring emails from your own Gmail or Outlook account, on any schedule. It is not an alternative for Boomerang's other features: it has no follow-up reminders, tracking or inbox pause.
Can Gmail send recurring emails without Boomerang or Recurrr?
Not on its own. Gmail's "Schedule send" sends a single email at a single time. To repeat an email you need an extension such as Boomerang, a dedicated tool such as Recurrr, a Google Apps Script, or an automation builder. Our guide to recurring email in Gmail walks through each one.
Do recurring emails from Boomerang and Recurrr come from my own address?
Yes, in both cases. The emails are sent through your own Gmail or Outlook account, so recipients see a normal email from you and replies go to your usual inbox.
Can I use both?
Yes. They do not conflict. You could keep Boomerang's free plan for the occasional follow-up reminder and use Recurrr for the emails that repeat.
