If you are writing an email and hesitate between then and than, the answer is simple: then relates to time or sequence, and than is used for comparisons. In email writing, choosing the wrong word can make your message unclear or unprofessional. This guide explains the difference clearly, gives you practical examples for real email situations, and helps you avoid the most common mistakes.
Quick Answer
Then = next, after that, or at that time. Example: “I will review your report, and then I will send you feedback.”
Than = used to compare two things. Example: “Your proposal is more detailed than the previous version.”
In emails, use then to describe steps, timelines, or results. Use than when you are comparing quantities, quality, or preferences.
Understanding the Core Difference
Both words sound similar, but their functions are completely different. Mixing them up is one of the most common writing errors, even among native speakers. In professional emails, this mistake can distract your reader and reduce your credibility.
Then: Time, Sequence, and Results
Then is an adverb that answers “when?” or “what happens next?” It connects events in time or shows a logical result.
- Time: “We will meet on Monday, and then finalize the contract.”
- Sequence: “First, complete the form. Then, submit it to HR.”
- Result: “If the client agrees, then we can proceed.”
Than: Comparisons
Than is a conjunction or preposition used to introduce the second part of a comparison. It always follows an adjective or adverb in the comparative form.
- Quantity: “We received more orders than last month.”
- Quality: “Her presentation was clearer than mine.”
- Preference: “I would rather work remotely than commute every day.”
Comparison Table: Then vs. Than in Emails
| Word | Function | Email Example | Common Mistake |
|---|---|---|---|
| Then | Time, sequence, result | “Please review the draft, and then share your comments.” | Using “than” for sequence: “Review the draft than share comments.” |
| Than | Comparison | “This option is cheaper than the alternative.” | Using “then” for comparison: “This option is cheaper then the alternative.” |
| Then | Logical outcome | “If the deadline is tight, then we need to prioritize.” | Using “than” in conditional sentences. |
| Than | Preference | “I prefer email than phone calls.” (Incorrect: should be “to”) | Using “than” after “prefer” (correct: “prefer X to Y”). |
Formal vs. Informal Tone in Emails
Both then and than are neutral words. They work in any tone, but the context matters.
- Formal email: “We will analyze the data, and then we will prepare a report.” (Clear sequence, professional tone.)
- Informal email: “Let me finish this, then I’ll get back to you.” (Casual, friendly.)
- Formal comparison: “Your proposal is more comprehensive than the previous one.” (Objective, polite.)
- Informal comparison: “This plan is better than the old one.” (Direct, conversational.)
In email writing, using the wrong word can break the flow. A formal email with “than” instead of “then” looks careless. An informal email with the same mistake can confuse the reader.
Natural Examples in Email Contexts
Here are realistic email sentences that show how then and than are used correctly.
- “I will update the spreadsheet, and then I will send it to the team.”
- “If you have any questions, then please let me know.”
- “The new system is faster than the old one.”
- “We need more time than originally planned.”
- “First, confirm your attendance. Then, I will book the venue.”
- “Her response was more detailed than I expected.”
Common Mistakes with Then and Than in Emails
Even experienced writers make these errors. Here are the most frequent ones and how to fix them.
Mistake 1: Using “than” for sequence
Wrong: “Please review the document, than send it to the client.”
Right: “Please review the document, then send it to the client.”
Why: The action is sequential, not comparative.
Mistake 2: Using “then” for comparisons
Wrong: “This option is better then the other one.”
Right: “This option is better than the other one.”
Why: “Better” is a comparative adjective, so it needs “than.”
Mistake 3: Confusing “rather than” with “then”
Wrong: “I prefer email rather then phone calls.”
Right: “I prefer email rather than phone calls.”
Why: “Rather than” is a fixed phrase for preference or choice.
Mistake 4: Missing “then” in conditional sentences
Wrong: “If you agree, than we can move forward.”
Right: “If you agree, then we can move forward.”
Why: “If… then” is a standard conditional structure.
Better Alternatives and When to Use Them
Sometimes you can replace then or than with other words to make your email clearer or more formal.
- Instead of “then” for sequence: Use “after that,” “subsequently,” or “next.” Example: “We will review the budget. After that, we will make a decision.”
- Instead of “then” for result: Use “as a result,” “therefore,” or “consequently.” Example: “The client approved the proposal. Therefore, we can start the project.”
- Instead of “than” in comparisons: Use “compared to” or “in comparison with.” Example: “This model is more efficient compared to the previous one.”
Use these alternatives when you want a more formal tone or when the sentence feels awkward with “then” or “than.” In most everyday emails, the simple words are perfectly fine.

FAQ: Then and Than in Emails
1. Can I use “then” at the beginning of an email sentence?
Yes, but it is more common in informal emails. For example: “Then, I will send you the invoice.” In formal emails, it is better to use “After that” or “Subsequently.”
2. Is it ever correct to use “than” after “different”?
No. The correct phrase is “different from” (or “different to” in British English). “Different than” is common in American English but is considered less formal. In professional emails, use “different from.”
3. What about “more than” vs. “more then”?
Always use “more than” for comparisons. “More then” is incorrect. Example: “We need more time than we have.”
4. How can I remember which word to use?
Think of then as related to time (both have an “e”). Think of than as related to comparison (both have an “a”). A quick trick: if you can replace the word with “next,” use “then.” If you can replace it with “compared to,” use “than.”
Final Tips for Email Writing
Always proofread your emails before sending. Read the sentence aloud. If it sounds like you are describing a sequence, use then. If you are comparing two things, use than. This simple check will help you avoid a common mistake that can make your writing look unpolished.
