Every time you switch from one type of task to another — from writing a report to answering emails to reviewing a spreadsheet — your brain pays a tax. Psychologists call it "switching cost," and research suggests it can eat up 40% of your productive time.
Batch processing is the antidote. Instead of doing tasks as they come, you group similar tasks together and knock them out in dedicated blocks.
Without batching, a typical morning might look like this: answer an email, write part of a report, answer another email, join a call, answer three more emails, go back to the report, check Slack, answer an email. You've been "busy" for four hours and the report is 20% done.
With batching: write the report from 9-11 (done), process all emails from 11-11:30 (done), take calls from 11:30-12:30 (done). Same four hours, dramatically different output.
When you do similar tasks in sequence, your brain stays in the same mode. Writing emails uses the same mental muscles — tone calibration, brevity, response framing. Writing a report uses different muscles — analysis, structure, argumentation. Switching between modes takes time and energy, even when you don't notice it.
Batching also reduces decision fatigue. Instead of deciding "what should I do next?" fifty times a day, you decide once per batch: "Now I'm doing email. Now I'm doing calls. Now I'm doing creative work."
Toodledo makes batch processing practical through contexts and saved searches. Here's the setup:
Create contexts for task types. Contexts in Toodledo represent the setting or mode of a task. Create contexts like: @email, @calls, @writing, @errands, @admin, @review. Assign each task to its appropriate context when you create it.
Build saved searches for each batch. Create a saved search for each context: "Show me all tasks with context @email that are due today or overdue." When email-processing time comes, pull up this search and work through every item.
Schedule your batches. Decide when you'll do each type of work. Many people find a rhythm like this: creative/deep work in the morning, email and admin after lunch, calls in the early afternoon, review and planning before end of day.
The email batch. Process email 2-3 times per day, not continuously. During each batch, handle every message: reply, delegate, defer, or delete. Use Toodledo to capture any action items that emerge, then close your email until the next batch.
The admin batch. Expense reports, form submissions, scheduling, file organization — all the small administrative tasks that individually take 5 minutes but collectively consume hours. Group them into a weekly admin block and blast through them.
The communication batch. Phone calls, Slack messages, and follow-ups share the same mental mode. Batch them together. Make all your calls in sequence, respond to all pending Slack threads, send all follow-up messages.
The review batch. Document reviews, code reviews, proposal reviews — anything where you're evaluating someone else's work. Batching reviews improves consistency because you're in "review mode" throughout, applying the same standards.
The creative batch. Writing, designing, strategizing — work that requires deep focus. Protect these batches fiercely. No email, no Slack, no "quick questions." This is where your highest-value work happens.
Batching works best when you plan your week in advance. Spend 15 minutes every Sunday or Monday morning in Toodledo:
Review all tasks due this week. Assign contexts if they don't have them. Estimate time for each batch. Map batches to your calendar — literally block time for "Email batch," "Admin batch," "Deep work."
This planning session pays for itself many times over. Instead of starting each day wondering what to do, you start knowing exactly what batch you're in and what it contains.
Some things can't wait for a batch. A client emergency, a time-sensitive decision, a system outage — these override the schedule. The goal isn't rigid adherence to batches but a default mode of working that reduces unnecessary switching.
Also, if you're in a role that requires real-time responsiveness (customer support, executive assistant, operations), pure batching won't work. Instead, batch what you can — admin, planning, review — and accept that communication will be more continuous.
Don't try to batch everything at once. Pick one category — email is the easiest — and commit to processing it in 2-3 dedicated blocks per day instead of continuously. After a week, add another batch. Build the habit gradually.
The first week will feel uncomfortable. You'll worry about missing something urgent in email. You won't. And the hours you reclaim from constant switching will show up as finished projects, better writing, and less end-of-day exhaustion.
