This is just an entry Note to myself about the various Send Rates for some email services. I have been running into some issues sending mail to GMail and others so I figured I would document my efforts to understand their limits. The notes below are for sending USING a webmail account…I mostly Send TO a webmail account, but I imagine the limits would be similar. I will report more as I find it out.
My initial data comes from emailaddressmanager.com
Send email rate limit for webmail providers – Gmail, Yahoo! Mail, Hotmail, AOL, Lycos Mail
Sending mass emails from webmail email accounts
Most webmail email account providers, such as Yahoo! Mail or Google Gmail, allow users to send email by using the webmail browser interface or by using a SMTP connection with the email account SMTP server. No matter the way you send the emails (web interface or email client software), you must be aware of the “rate limit” (the limit for sending emails) established by your email account provider.
Web Email Account Providers – email rate limits and SMTP limit
Important note: Please do NOT take this information for granted, as your email account provider can change its email policy without any prior notification. It is always a good idea to contact your email account provider and ask about the email send rate, before proceeding with a mass email campaign.
