Frequently Asked Questions

What is email deliverability?

Email deliverability means “How much are your emails going into the inbox vs the spam folder?” Deliverability depends on many factors and is also closely related to the sophisticated spam filters used by the mailbox providers such as Gmail, Outlook, Yahoo and others.

How can I improve my deliverability?

Each email message gets assigned a spam score by the checking spam filter – if the spam score is above a certain threshold, then the message is directed to the recipient’s spam folder. The key to deliverability is to perform well on all fronts so that the spam filter assigns a low spam score to your email messages.

Important factors the spam filters consider are: The historical level of engagement (opens, clicks, replies), the reputation of the sending domain, the reputation of the sending SMTP server (IP address), the amount of bounced emails, the wording of the email message, the technical correctness of the email message’s source code (HTML), the technical correctness of the sending infrastructure, and more.

Can you explain the most important email terminology?

Email Authentication: On the Internet, anyone can pretend to be sending email from any email address and domain. So, technical means were created to prevent people from impersonating others or modifying email messages as they travel to the recipient. These technical means are called email authentication mechanisms and they generally include DKIM (DomainKeys Identified Mail), SPF (Sender Policy Framework), DMARC (Domain-based Message Authentication, Reporting & Conformance) and rDNS (reverse DNS). Each of these mechanisms serves its own particular purpose.

SMTP: An SMTP server, a.k.a. a mail server, is a piece of software that is able to send email messages. It stands for Simple Mail Transfer Protocol.

Reputation: There are two main types – domain reputation and IP reputation (which is the IP of the SMTP server). When you send emails, mailbox providers like Gmail and Outlook keep track of the sending history of your domain name and IP address(es). From your sending history and performance they build an internal measure of these reputations and their spam filters factor them in when determining where to place your email messages.

Do I have to restructure my current outreach setup if I want to use your service?

No need to. We have created a plug-and-play service. You can try it out for a new outreach campaign, or for an existing one on top of the sending you are already doing. If you like the results, you can increase the sending you do through our service.

How are you protecting data added to Mail Reach?

Security is of paramount importance. The high number of online attacks happening on companies around the world is due to a poor understanding of best security practices and lack of creating a high level of security at both the planning and implementation stages of company technologies and procedures.

At Mail Reach, we use industry-standard solutions and systematically apply best security practices. Our website is available using the latest encryption versions (which you can verify from the padlock icon on your browser). We mostly use software that has been battle-tested on millions of websites. Our hosting provider implements the strongest security (completely separate Linux containers) one can find in the industry. We use a Web Application Firewall which protects our website from new attacks in real time, and our servers are scanned every day. We always remain vigilant and up-to-date on what’s happening in the IT world and in the security industry and what new attacks are being employed. If any questions or concerns come up, get in touch.
