"Will I get blocked by my ISP/ESP if I send 1,000 emails per day?""How many emails can I send out per day?"… These are the frequently questions that 1and1Soft receives almost every day. Most of these customers are seeking the cheapest way to send out mass emails, and using free email services from Gmail, Hotmail or Yahoo! Mail.

The answer is: it depends.

Even though, officially, most email service providers have announced the daily quota, or sending limit of their SMTP server, the actual number may still vary by each email account's reputation score.

The sender score / reputation score is usually calculated by the bounce-back rate, spam rate imposed by the recipients and keywords filtering. If you send out too many emails within a short period of time that contains a lot of spam sensitive keywords, your reputation score is at risk. Next time, your ESP will limit your sending quota and lower your email deliverability.

In 1and1Mail, you can easily control how many emails you can send out per day. When you reach the limit, 1and1Mail will automatically stop sending, and resume after 24 hours. Try to send fewer emails per day at the beginning. When you gradually build up your reputation with your ESP, you can increase the number later.

1and1Mail Sending Policy Setting

In 1and1Mail 3.2, we are going to launch a new feature called "Auto IP Switcher" that can change your IP address automatically when you are sending your mass email campaigns. Why do you need it? How does it work?

1. Why do you need "Auto IP Switcher" in your email marketing software?

"Auto IP Switcher" can help us send more emails using free email accounts, such as Gmail, Hotmail, Yahoo! Mail and AOL Mail. But if you are using your corporate email accounts or paid email accounts, most likely you do not need this feature.

As we know, nowadays, most free email service providers have become very strict with mass mailing behaviors. None of them would like to become a victim of spammers. Therefore, they limit the daily sending limit of free email accounts in two ways:

(1) Daily quota of a single email account

On average, a single email account can send out 100 – 500 emails per day, depending on your account reputation with the service provider. To play safe, do not go over 100 per account per day, otherwise, your email account will be suspended soon. So, can I sign up multiple email accounts and send 100 × n emails per day? It depends on the following.

(2) Daily quota of multiple email accounts from a single IP address

To prevent you from sending mass mails by applying multiple email accounts, the service provider also sets a daily limit on number of emails from a single IP address. This is a very smart move because in most cases, one PC only has one IP over a certain period of time. It is difficult to send more emails with multiple email accounts under a single IP address.
 

2. How to get a new IP address to increase email deliverability?

The traditional way is: manually disconnect your Internet connection, and redial to reconnect.

In most cases, after you disconnect and redial, your PC  will be assigned a new IP address unless

(1) You connect to the Internet through a static IP.

(2) You connect to the Internet through a router. (You need to restart the router to get a new IP.)

(3) You connect to the Internet through the local network of your company or your school.
 

3. How to switch IP automatically in 1and1Mail?

To maximize the email deliverability, 1and1Mail uses a special way to do the IP switching. In 1and1Mail Personal Edition and Business Edition, you are allowed to add multiple email accounts from different email service providers, and also divide them into groups. 1and1Mail will change IP automatically based on groups, not based on a fixed time interval. Please follow the 3 steps as below:

Auto IP Switcher

(1) Enter your username and password in Redial Setting for Auto IP Switcher. (Tools -> Settings -> Auto IP Switcher)

(2) When you start the sending, 1and1Mail will select a certain number of email accounts from the same ESP (email service provider). For example, 2 email accounts from Gmail, 2 email accounts from Hotmail, 2 email accounts from Yahoo! Mail, 2 email accounts from AOL Mail. Since each of them are from different ESPs, it can fully take advantage of the power of a single IP address.

(3) 1and1Mail send mass emails out using the email addresses in Step 2 by turns. For example, send 20 emails through each email address. After it is finished, 1and1Mail automatically disconnect the Internet and redial to get a new IP, and then continue the sending through another group of new email addresses again.

1and1Mail 3.2 will be launched in Nov 2011. You can download the Free Edition it from here. But since 1and1Mail Free Edition only allows 1 email account, the Auto IP Switcher only makes sense in Personal and Business Edition.

 

Free email service providers, such as Gmail, Hotmail, Yahoo! Mail and AOL Mail, usually provide free SMTP connections to send emails and they are the most commonly used channels for mass mailing.

When using the free service, you should pay special attention to the send limits and rate limits imposed by these free email providers. Through using well-recognized mass mailing software and configuring it properly, you can easily go over the limits and save significant marketing cost.

The following data is mostly collected from the official sources (namely, the official websites of Gmail, Hotmail, Yahoo! Mail and AOL Mail). But your email service provider may change its mailing policy without any prior notification. It is suggested you always contact your email service provider and ask about the most updated SMTP email send limits and send rate before proceeding with your email marketing campaigns.
 

Send unlimited emails

 

Gmail Sending Limit and Send Rate

Gmail Send Limits: 100 people / connection
Gmail Send Rate: 100 people / day
Gmail Attachment Size Limit: 25MB
Gmail Restriction Expiry Method: Recovered within 24 hours after the limit is reached

Gmail will temporarily disable your account if you send emails to more than 500 recipients or if you send a large number of undeliverable messages.

If you use a POP or IMAP client (e.g. Microsoft Outlook, Mozilla Thunderbird or Apple Mail), you may only send a message to 100 people at a time. Your account should be re-enabled within 24 hours.

Please do verify your contacts' email addresses. It's also important that everyone you are sending mail to is willing to receive it.

Hotmail Sending Limit and Send Rate

Hotmail Send Limits: 100 messages / connection
Hotmail Send Rate: 100 people / day
Hotmail Attachment Size Limit: 25MB
Hotmail Restriction Expiry Method: N/A

The Hotmail limit for outgoing email messages is 100 messages per day. However, it is not a fixed number!

The limit also depends on your reputation within Hotmail. The system needs a few days to build your reputation. So, there are stricter limitations on new accounts or accounts that have engaged in activity representative of abusers sending spam. As you develop a reputation for not sending junk e-mail, Hotmail increases the number of recipients that you can send messages to.

If you are a new free user, you might be limited to a lower limit compared to an older account which is a temporary restriction and is upgraded to the maximum recipients limit as soon as the user establishes credibility in the system.

You can verify your account with a mobile number (only available in limited markets at this time): http://g.live.com/1rewlive4tup/tupp to increase the limit immediately. Please note that the SMS validation will increase the limit only if you are hitting a lower limit compared to a regular free user. If you already have the maximum limit of a free account, SMS validation will not help in increasing the limit.

Or, you can upgrade to Hotmail Plus or MSN Premium, both of which are paid accounts, to enjoy a higher sending limit.

Yahoo! Mail Sending Limit and Send Rate

Yahoo! Mail Send Limits: 20 people / connection
Yahoo! Mail Send Rate: 100 people / day
Yahoo! Mail Attachment Size Limit: 25MB
Yahoo! Mail Restriction Expiry Method: N/A

Yahoo! Mail accepts a maximum of 20 messages per SMTP connection. It is suggested you cap the number of messages you send to Yahoo! Mail to fall within this per-connection limit. When this limit is reached, no further messages will be accepted for delivery as Yahoo! Mail server automatically terminates the connection (without giving an error code).

If you are sending messages to a significant number of Yahoo! Mail users, you may try to reconnect to Yahoo! Mail MX servers immediately thereafter.

You may open concurrent connections from the same server to facilitate efficient transmission of your messages under the help of email marketing software.

Yahoo! Mail also keeps reputation data about each IP address and domain you send from. Therefore, by segmenting the mail stream that delivers marketing mail from another that sends transactional messages, you make it easier for Yahoo! Mail to determine and assign each mail stream's reputation.

If you use Yahoo! Mail Plus, the outbound email messages are limited to 500 per day, and each message can be sent to no more than 100 contacts at once.

AOL Mail Sending Limit and Send Rate

AOL Mail Send Limits: 200 / connection
AOL Mail Send Rate: Constantly changing
AOL Mail Attachment Size Limit: 25MB
AOL Mail Restriction Expiry Method: N/A

AOL also imposes a rate limit on an AOL member when a member exceeds the acceptable number of email messages sent in a given time period. Rate Limits have been put in place by AOL Mail to curtail abuse from spammers and ensure an enjoyable online experience. The maximum number of people you can send an email to is constantly changing so that spammers cannot find out what it is. If you need to send an email to a large group of people, please break your mailing list into the smallest groups possible.
