To maximize the email deliverability of a mass mailer, many email marketers sign up for multiple email accounts in order to exceed the daily quota and send more emails per day. Oftentimes, they would like to customize the "Sender's Email" and make it look like all mails are sent from one account. 1and1Mail do offer such kind of functionality (Setting -> Default -> Sender's Email). However, nowadays, as more and more people misuse this feature to steal money in the guise of a legitimate and well-known company, many email service provider has disable this feature and would always show to the recipient the real email account that is sending the email.

The rise of phishing emails block the way of customizing your sender's address. What does a phishing email look like?

We’ve included an actual example below. The phishing email has been captured as an image, so hotlinks are disabled. In this attempt, cybercriminals were trying to get Shahin to enter his Facebook credentials, purportedly to register another address, so they could capture his real Facebook credentials and take over his account.

Key email phishing tip offs:

·         The “From” field: always look at the actual “mail to” address shown in brackets. In the example, notice it is NOT an @facebook.com address.

·        Spelling Errors: Bad grammar and spelling can be immediate indicators of a phishing scam. Large companies have marketing teams and proofreaders that catch most of these errors before emails get sent.

·         The Hotlink: If you hover over the link shown in the body of the email, you can see where the URL will actually take you. In the example, notice it is NOT a facebook.com domain.

o   Some cybercriminals will go a step further to make their URL look ok at first glance.  For example, by registering a domain name called faceb00k.com (using zeros instead of the letter O).

 

"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.

Now, you are ready to send out your first email marketing campaigns through GoDaddy email account with professional email marketing software.

When you are sending mass emails with 1and1Mail, sometimes you will see a pop-up message saying "You have reached the daily sending limit. The limit may be imposed by your email service provider or your setting in 1and1Mail." This is usually caused by the following:

1. You have reached the maximum sending amount you have set in 1and1Mail. To increase the sending amount, go to Account Manager, double click the email account you are using, and adjust the number under Sending Policy tab of that account. (1and1Mail suggests you not send more than 100 emails per account in 24 hours.)

2. You have reached the daily sending limit imposed by your email service provider (Gmail, Hotmail, Yahoo! Mail, AOL Mail, GoDaddy, etc.). At this moment, your email accounts or IP addresses may be suspended and it will not be recovered until 24-48 hours later. You can verify this by viewing the Reports. If the last few emails cannot be sent successfully, it is most likely your email accounts are temporarily suspended.

To prevent this from happening in future, there are several things you can do:

  • Send emails to double opt-in contacts only, which means, you should always obtain your recipients' permission before sending mass emails. Unsolicited emails will get you a lot of spam complaints within a short period of time. If that happens, no matter what email clients or email accounts you use, they would be suspended very soon.
     
  • Mimic manual sending by generating random time lag and content spin. The main reason that your email service provider blocks you is because they think you are using a automatic mass mailer spamming thousands of people. With 1and1Mail, you can generate random time lag between sending each email, and also spin different sets of contents in the email subject, body and attachments. This way, you are like a real person manually sending each individual email that looks different to everyone, not a robot trying to spam the world.
     
  • Always remove bounced and unsubscribed from your contact list. Keeping sending to bounced and unsubscribed emails would lead to high bounce rate and spam complaints of your email campaign. Such behavior is harming the email ecosystem, thus, it will seriously lower your Sender Score. Therefore, constantly removing bounced and unsubscribed emails from your contact list is very important to your email deliverability and future revenue stream.
     
  • Use advanced SMTP servers (e.g. turboSMTP) with 1and1Mail. Advanced SMTP servers provide a guarantee on the number of emails you can send out per day or per month through their SMTP connections and high email deliverability.
     
  • Use proxy servers to manage multiple email accounts. Most email service providers set a daily limit on how many emails one can send per hour or per day (Regarding the daily sending limit and send rate of commonly used email accounts, please refer to here). If you want to go over the limit, you can use multiple email accounts with proxy servers in 1and1Mail.

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.

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.
