To connect your Yahoo email account to a third-party email client (such as Outlook, Apple Mail, or Thunderbird), you’ll need to configure your **IMAP (incoming)** and **SMTP (outgoing)** server settings. ### Automatic Setup (Recommended) On the setup page, look for the section labeled **Service Provider**. From the dropdown, simply select **Yahoo** then click **Apply**. ![](https://help.startups.com/hs-fs/hubfs/image-png-Apr-08-2026-04-05-13-8179-PM.png?width=527&height=112&name=image-png-Apr-08-2026-04-05-13-8179-PM.png) Once applied, the system will automatically populate all the correct connection details for you — including SMTP, IMAP, ports, and encryption settings. No manual configuration is needed. This method ensures a quick and accurate setup, minimizing potential errors. --- ### Manual Setup #### 📥 Incoming Mail (IMAP) Server Use these settings to receive incoming emails: - **Server:** imap.mail.yahoo.com - **Port:** 993 - **Requires SSL:** Yes IMAP allows you to sync your email across multiple devices while keeping messages stored on Yahoo’s servers. --- #### 📤 Outgoing Mail (SMTP) Server Use these settings to send emails: - **Server:** smtp.mail.yahoo.com - **Port:** 465 or 587 - **Requires SSL:** Yes - **Requires Authentication:** Yes SMTP is responsible for sending outgoing emails through your Yahoo account. #### ⚠️ Important Notes - To connect your **Yahoo email to Investor Matching**, you need to use a [**Yahoo app password**](https://help.startups.com/knowledge/how-to-generate-a-yahoo-app-password-for-investor-matching-email-setup?hsLang=en) instead of your regular account password. - Make sure **SSL/TLS encryption** is enabled. For outgoing mail, use **Port 465 (SSL)** or **Port 587 (TLS)**. If you're seeing an error similar to the one below when connecting your Yahoo email account: **"SMTP: Invalid login: 535 5.7.0 (#AUTH005) Too many bad auth attempts; IMAP: Command failed"** This usually indicates an authentication issue with your Yahoo account or the app password being used. To resolve this, please check the following: 1. **Verify your Yahoo account.** Make sure you're generating the app password from the same Yahoo account as the email address you're trying to connect. 2. **Generate a new app password.** If the current app password isn't working, try generating a new one through your Yahoo account's security settings. 3. **Check the password entered.** Make sure you're entering the generated app password correctly, without any extra spaces or missing characters. If you've tried these steps and the error continues, Yahoo may be temporarily restricting sign-in attempts due to multiple failed logins. Wait a while before trying again. - [Startups.com Customer Support](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#main-content) - [Account Subscription](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#account-subscription) - [Membership Features](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#membership-features) - [Investor Matching](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#investor-matching) - [Perks and Benefits](https://help.startups.com/knowledge/startups-com-customer-support?hsLang=en#perks-and-benefits) - [Startups.com Site Content Help](https://help.startups.com/knowledge/startups-com-site-content-help?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/startups-com-site-content-help?hsLang=en#general) - [Fundable](https://help.startups.com/knowledge/fundable?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/fundable?hsLang=en#general) - [Getting Started on Fundable](https://help.startups.com/knowledge/fundable?hsLang=en#getting-started-on-fundable) - [Equity Campaigns](https://help.startups.com/knowledge/fundable?hsLang=en#equity-campaigns) - [Creating a Fundable Profile](https://help.startups.com/knowledge/fundable?hsLang=en#creating-a-fundable-profile) - [Investors](https://help.startups.com/knowledge/fundable?hsLang=en#investors) - [Legal](https://help.startups.com/knowledge/fundable?hsLang=en#legal) - [Payments & Fees](https://help.startups.com/knowledge/fundable?hsLang=en#payments-fees) - [Clarity.fm](https://help.startups.com/knowledge/clarity-fm?hsLang=en#main-content) - [General](https://help.startups.com/knowledge/clarity-fm?hsLang=en#general) - [Calls](https://help.startups.com/knowledge/clarity-fm?hsLang=en#calls) - [Member FAQs](https://help.startups.com/knowledge/clarity-fm?hsLang=en#member-faqs) - [Expert FAQs](https://help.startups.com/knowledge/clarity-fm?hsLang=en#expert-faqs) - [Privacy & Security](https://help.startups.com/knowledge/clarity-fm?hsLang=en#privacy-security) - [Payments & Fees](https://help.startups.com/knowledge/clarity-fm?hsLang=en#payments-fees) - [Getting Started on Clarity](https://help.startups.com/knowledge/clarity-fm?hsLang=en#getting-started-on-clarity) - [Your Clarity Account](https://help.startups.com/knowledge/clarity-fm?hsLang=en#your-clarity-account) - [Frequently Asked Questions](https://help.startups.com/knowledge/clarity-fm?hsLang=en#frequently-asked-questions) - [Bizplan](https://help.startups.com/knowledge/bizplan?hsLang=en#main-content) - [Customizing Plan](https://help.startups.com/knowledge/bizplan?hsLang=en#customizing-plan) - [Getting Started](https://help.startups.com/knowledge/bizplan?hsLang=en#getting-started) - [Managing Account](https://help.startups.com/knowledge/bizplan?hsLang=en#managing-account) - [Finance](https://help.startups.com/knowledge/bizplan?hsLang=en#finance) - [Support](https://help.startups.com/knowledge/bizplan?hsLang=en#support) - [Companies](https://help.startups.com/knowledge/bizplan?hsLang=en#companies) - [Publishing](https://help.startups.com/knowledge/bizplan?hsLang=en#publishing) - [Launchrock](https://help.startups.com/knowledge/launchrock?hsLang=en#main-content) - [Custom URLs / DNS Settings / Using Your Domain](https://help.startups.com/knowledge/launchrock?hsLang=en#custom-urls-dns-settings-using-your-domain) - [General Questions](https://help.startups.com/knowledge/launchrock?hsLang=en#general-questions) - [Getting Started on Launchrock](https://help.startups.com/knowledge/launchrock?hsLang=en#getting-started-on-launchrock) - [Video Tutorials](https://help.startups.com/knowledge/launchrock?hsLang=en#video-tutorials) - [Your Launchrock Account](https://help.startups.com/knowledge/launchrock?hsLang=en#your-launchrock-account) - [Payments & Fees](https://help.startups.com/knowledge/launchrock?hsLang=en#payments-fees) - [Blog](https://help.startups.com/blog) [![Chill listening crop-3](https://help.startups.com/hs-fs/hubfs/startupscom-logo-420.png?width=84&height=24&name=startupscom-logo-420.png "Chill listening crop-3")](https://startups.com) Copyright © 2026, Startups.com
