Let us try to find out whether sending email is safe. We begin email is an ancient technology compared to modern team communication tools, and it has technical limitations that make its age a real barrier to security. Fortunately for its four billion users, developers and security researchers are constantly coming up with ways to improve on this old technology to be viable and secure in an era of rapid and intelligent attacks.
Security features to look for in an email service
You probably already use Gmail or Outlook. What’s wrong with those services? Are they not safe? Well, it depends on your threat model and adversary.
If you are an enemy of a large organization or state, the biggest differences are between security-focused and regular email, but can be seen as overkill by everyday users.
For example, the location of the server can only be appropriate if you are a worker who can expect the government to reduce its communication. On the other hand, end-to-end encryption can help both individuals and businesses keep their information secret: unencrypted email was blamed for at least four major breaches of the past few years, millions of emails leaked, and millions The dollar could be avoided. Damage.
Below are the features you’ll often find as part of a secure email, as well as an idea of why and what they may not be for you.
End-to-end encryption

To understand end-to-end encryption, you first need to understand encryption.
Encryption is a way to obscure data. https Any website in its URL is using Secure Sockets Layer (SSL) so that you can protect the data as it travels from your computer to the website’s server. SSL provides a way for your computer to ensure that it sends the data it sends and receives from an SSL-enabled server. Nearly all websites you visit regularly will be able to protect users by getting their passwords to SSL or “tapping the line” as input stolen by someone.
The same goes for email data: sending an email over an encrypted network means scratching the contents of the plain text of the email so that it is impossible to read a key without encryption, which acts like a password.
Modern encryption works so well that it would take a million computers to work for sixteen million years to crack it, but non-security-focused services like Gmail and Hotmail encrypt data only because it runs from your computer to their servers. She goes. On the other hand, it can be clearly read. Users need to believe that these organizations will not use their encryption keys to read your email – or that it will not fall into the hands of hackers.
End-to-end encryption puts control in the hands of the user. When you load your inbox with an end-to-end encrypted email service, it first needs to obtain a private key, specific to your account — and essentially un-backed — before the encrypted content De-scrambles up. Unless you are manually encrypting email, this process occurs in the background for all end-to-end encrypted tools.
Encryption is a difficult problem for computer scientists and can be resource-intensive to implement. It is only in recent years that both end-to-end encryption has become the standard thanks to the increased paranoia of the public following events such as messaging apps like WhatsApp and NSA leaks of Snowden, which shows that the world’s governments To what extent do they monitor their citizens? Even Google’s systems were not safe from prying eyes.
If an email service that uses end-to-end encryption is forced by authorities to hand over its data, it will only be able to provide useless data to someone without the user’s private encryption key.
We also try to learn some other types like
PGP encryption
Sundar Good Privacy, or PGP, was developed in the 1990s to guarantee the security and privacy of email communications over insecure networks. Its basic concept involves the use of private and public copies, and is implemented today in secure communications devices such as ProtonMail and Signal.
When you send an email encrypted with PGP, you use your public key like a padlock to secure content, in addition to using your password to authenticate with your email service. The recipient then uses their private key to unlock and read the message. Public and private keys are long strings of text just like passwords.
An important information
PGP is an open source technology and has been implemented by various developers and organizations. In 2018, it was found that some of these implementations suffer from a security flaw that could allow hackers to decrypt HTML email if the account was previously compromised. This defect affects email clients such as Outlook, Apple Mail, and Thunderbird, but none of the services are on this list.
We can authenticate it in two ways like
Two-factor authentication adds an extra layer of security to your email accounts which makes a cracked password useless and the hacking process becomes increasingly more difficult. This is because it depends on two things:
- Something you know like a username and password
- You have something, such as your mobile phone or a backup key
It becomes very important to keep these things in mind, we have shown some things below.
It does not make sense to trust the integrity of your password. Have I found a database of sensitive information obtained from worldwide hacks, with more than 320 million passwords on file. Passwords are routinely hacked, leaked, and used to compromise victims’ accounts. A hacker is likely to have access to both your password and your phone or physical backup, however, it is rare.
Bi-factor authentication is implemented in many different ways, but the most common is the use of one-time tokens. When you tap on the Google app to sign in from a new computer, you are sending a unique token to the server, which can only be used once. The same goes for getting a code on SMS to log in to Twitter. This prevents it from leaking or being used for continuous use. Recovering your account also becomes easy if you lose access.
Open Source
Open source software, like the Android operating system and Firefox browser, is software that makes its source code available to users, developers and the community to observe and improve. This is in contrast to something like Microsoft Outlook, which is packaged as an executable file that cannot be inspected or audited.
What does the way a device’s source code is treated have to do with security?
Well, when you are using an email service like Outlook, you are placing your faith in the fact that Microsoft developers are working in good faith by not adding anti-user features and (b) enabling software to a Secure system is built.
If the software is open source, such a leap of faith is not required. Open source projects are developed with complete transparency as they succeed and improve. Insects are made public knowledge, and large projects are equipped with thousands of dedicated debuggers.
This type of investigation is good, and it is possible with open source. In fact, this is one of the reasons why the Linux operating system was developed so quickly and rapidly despite being a project of a bedroom hacker and group of volunteers.
Metadata handling
Do we know that when you send an email, you are also transmitting information about your computer, web browser, network and recipient?
This data is stored in email header metadata, and secure email services usually exclude it. Remember, when you are dealing with security, you are also dealing with smart human beings trying to make available information about your life, habits, and preferences. If you don’t think of metadata cases
Collab Now (web)
Do we know that there are options of G Suite and Office 365
With email, calendar, contacts, and file storage, Collab Now is on the market as a secure alternative to G Suite and Office 365.
Collab Now was developed for the German Federal Office of Internet Security and was used primarily in Germany until it received mainstream media attention in the wake of NSC leaks. Groclav founder Pamela Jones revealed that she was visiting Collab Now’s email address the same day she closed the site in 2013:
If you have to stay on the Internet, my research suggests that security ranging from surveillance to short-term, even possible use a collab-like service for email, which is based in Switzerland, and therefore under different laws Is under Compared to the US, laws that try to give citizens more privacy.
Collab Now is fully open source and provides advanced security features. Although it is missing end-to-end encryption (outside of its desktop client), it supports true forward secret (PFS), which means that encryption keys are short-lived: if encrypted content falls into the wrong hands, it Will not be usable with any key other than the disposable used in that session.
For mobile access, you can use webmail in your POP3 / IMAP client such as iOS Mail via your device’s browser or hook collab. Collab Now also supports SMTP, CalDav and WebDAV protocols, so if your business systems are already integrated with one of these protocols, this may be a plus.
We will further discuss why it is important to be aware of the limits of sending emails.
If you’re sending your cold email using tools like Woodpecker, which sends email from your own mailbox (your own SMTP), your email service provider has limitations to keep track of when setting up your cold email campaigns. Occur.
Woodpecker does not internally limit the number of emails you send a day, but your provider does. Sending multiple emails in a day (or sometimes too many hours, or even a minute) can block your email account, meaning you will not be able to send any type of email from this account for 24 hours or more.
If you know the limits, and set your delivery time and the number of emails sent per campaign according to those limits, your campaigns will be planned smoothly and your emails will not be considered spam – provided you are not without Sending poor quality content of a personalization.
If you are sending spam or anything that is considered spam by your recipients, you will be blacklisted anyway and possibly reach your new limit as soon as possible. Remember: If you want to avoid being blacklisted, then delivery of your cold email is also important.
Email sending limits are for all messages originating from your address, sent from your address. That’s why if you have several follow-up plans within your campaign, you should keep in mind that after a few days or weeks, not only will your first touch email be queued to send one day, but there will also be many follow-ups. As all defined types of emails overlap, boundaries can be easily exceeded. Same goes for sending some campaigns from the same email address at the same time.
It is also very important to know some points, you should also ensure this
- How many emails can Gmail send per day,
- How many emails you can send with Yahoo,
- How many emails can Outlook.com send at a time,
- What are some other popular email hosts sending email,
- How many emails are considered spam and how to avoid being blacklisted.
So let us tell how much there can be a limit to sending free Gmail emails.
Per day: Maximum 100 messages via SMTP (but 500 emails via browser). Please read it >>
Hourly: No official information. However, from our experience, sending more than 20 messages an hour from a free Gmail account is good.
Extra good-to-know: If you are more than Gmail sending quota, your account will be blocked for 1-24 hours. We generally do not recommend sending cold email campaigns to a regular free Gmail account, but instead set an address to a different domain using G Suite (business email service from Google). This gives you more opportunities in the form of outreach volume and more control over your sending settings. Read more about the difference between a free email account and a custom domain email here.
Also, your recipients will certainly treat you more seriously if they receive an email from an address including a business domain instead of name267@gmail.com. So if you decide to use a free Gmail account for your outreach anyway, make sure the address is secure and valid for your recipients. See why cold email is so important off line in outreach.
However, it is most important to keep in mind that controlling the amount of your outreach is one thing, but also the quality of care. If you send poor quality cold emails to a non-verified address without any validation, your provider may block you before the quantity limit. Especially if your provider is Gmail. So keep in mind that quality is also more important than quantity in this regard.
I am telling you one more thing that if you send email to G Apps (Google Apps for Business) then it is very important to know about it
Per day: 2000 messages (500 on trial)
Hourly: Officially, there is no hourly limit
Additional good-to-know: If you cross the limits, your account will be blocked for 24 hours.
Just like in the case of a free Gmail account, the quality of your messages is very important for deliverability, and poor delivery can cause your account to be blocked before your account reaches the volume limit. Therefore, if you are blocked from sending a limited number of messages, check your email copy for spam words, broken links, HTML-to-text rate and lack of personalization.
If Google’s anti-spam mechanism found something that might suggest your email to be spam, you would be blocked. It matters a lot if you think about it: The most effective way to prevent spam from getting into people’s inboxes is to stop people from sending spam for the first time.
Important G Suite information: After upgrading your account from trial to premium in G Suite, you will not automatically have 2000 messages to send one day. To increase your limit you need to wait. But soon your limits may increase.
Another important thing is that we should consider it as a warning or instructions
BTW, beware of spikes in your mailbox activity
It is always a good idea to set a longer period for sending messages to prospects to a larger group, because then particular messages are being sent less often, and there are no spikes in the activity of your email account. If you have an email account dedicated to outbound, and barely send anything from this account on a daily basis, but then suddenly you are trying to send 300 emails in the course of an hour, this is for any email provider Seems suspicious. The key is to organize your outreach in a way that will allow a fluent, steady flow of outgoing messages.
I’m sure someone told you at least once in their lives that there are some “golden hours” to send emails (you know for sure, “Don’t send on Monday, send on Tuesday before lunch” “). So it is possible that you are sent on Tuesdays between 10 and 11 am to schedule all your campaigns. Well, brace yourself and resist this temptation! This is not a newspaper – it’s cold email.
And I believe that there is no such thing as a universal “golden hour” for sending email. You need to search for “golden hours” for your specific prospect group. And if you send automatically, give your email just over an hour to avoid being blocked for a dangerous, unnatural spike in your mailbox activity.
The most important thing is that copying inappropriate or deeply personal emails to a colleague or group of unfamiliar peers can be embarrassing enough. But if you send secret documents without secret to the wrong people, you can cause a serious security breach, and quickly expel you and your employer in very hot water. Find out how to stay safe on the email below.
Very important information at a glance
Encrypt password-protected and confidential documents before sending them.
Send password to recipient via means other than email.
Always double-check who you are emailing.
Use ‘BCC’ when sending emails to large groups or email lists.
To your email account.
