3 ways bulk email verification can prevent free trial abuse
Businesses have learned how to mend the weak spots in free trial marketing.
- Free trials are an excellent marketing tool but people can take advantage of the system by using disposable emails, jumping from one free trial to the next.
- You can use free trial marketing to great effect if you know how to protect your business against those who want to take advantage.
- Here are 3 ways to identify email addresses that will never lead to a genuine sale and remove them from your lists.
Isn't it a fundamental consumer right to try a product or service before purchase to make sure it works? Then again, not all consumers are as ethical as we would like to believe. Quite a few never end up purchasing licenses or subscriptions and are content with abusing free trials by primarily using disposable email addresses. Companies can, however, fight back against free trial abuse with the help of a bulk email validation solution. Here are three ways how.
Limit registration to non-disposable email address users
Protection against freemium abuse begins upon signup. Limiting registration to only those who don't use disposable email addresses is one way to do that. You can integrate a bulk email verification API into your registration page or use a disposable email domains database like the one provided by WhoisXML API to automatically check if the email address a subscriber provided is disposable or not. A useful bulk email validation tool would tell your administrator immediately that the address is disposable, and so it's likely you're dealing with someone who might try to abuse a free trial.
Make sure the email address is contactable
Not all freemium abusers use disposable email addresses. Some can just as easily use personal email addresses from Gmail, Yahoo, or other free services. A lot of people keep extra email addresses to direct email marketing or newsletters to. It's one way to keep their primary personal inboxes less crowded.
Since these secondary email addresses probably get tons of marketing collateral each day, they're likely full, and so messages will sooner or later bounce. That's not good for any company as it translates to a high bounce rate, which can adversely affect its email deliverability and domain reputation.
A robust bulk email validation API can instantly let you know if all the email addresses in your contact database are accessible. It tells you if every address is Simple Mail Transfer Protocol (SMTP)-enabled and, therefore, able to receive messages. So, if you, for instance, have the email address firstname.lastname@example.org in your database, which has an email verification result that says it isn't SMTP-reachable, it may be best to take it off your distribution list to lower your bounce rate.
Taking the email address that's probably no longer in use off your subscription list is also advisable. That way, your chances of dealing with a freemium abuser is reduced as well.
Keep your distribution list in tip-top shape
The more unreachable email addresses in your distribution list, the higher the chances of ending up in someone's blacklist. It is, after all, not uncommon for spammers or cybercriminals to use the shotgun approach in attacks. Sending messages to as many inboxes as possible, after all, increases their chances of success. Using their tactic for a legitimate business, however, is unacceptable either. Organizations are not allowed to send emails to just about anyone without their consent.
And so companies that want to stay off blacklists should make it a point to keep their distribution lists updated at all times. But we also know that over time, contact lists can grow to a massive size, making cleanup tedious and time-consuming. The quickest way to keep email databases in tip-top condition is to use a bulk email validation solution. It lets you check up to 50,000 email addresses in one go to make sure that they won't do your domain reputation any harm and cause you to end up on a dreaded blacklist.
Bulk Email Verification API/Lookup can confirm if each email address:
- Has the correct syntax or follows established Internet Engineering Task Force (IETF) standards
- Is not disposable by checking its domain against those of known disposable email providers that include Mailinator, GuerrillaMail, and more than 2,000 others
- Has a corresponding mail server evidenced by properly configured mail exchanger (MX) records
- Points to a valid inbox that lessens your chances of dealing with suspicious users
- Is not associated with a catch-all mailbox that isn't assigned to any particular user and so may not add value to your distribution list
While allowing every potential subscriber to try your product/service free of charge is a great thing, you still need a way to keep the system honest. Strike a balance between keeping free trial abuse to a minimum and encouraging individuals to register for your offerings with the help of bulk email validation solutions.
Water may be far more abundant on the lunar surface than previously thought.
- Scientists have long thought that water exists on the lunar surface, but it wasn't until 2018 that ice was first discovered on the moon.
- A study published Monday used NASA's Stratospheric Observatory for Infrared Astronomy to confirm the presence of molecular water..
- A second study suggests that shadowy regions on the lunar surface may also contain more ice than previously thought.
Credits: NASA/Daniel Rutter<p>Still, it's not as if the moon is dripping wet. The observations suggest that a cubic meter of the lunar surface (in the Clavius crater site, at least) contains water in concentrations of 100 to 412 parts per million. That's roughly equivalent to a 12-ounce bottle of water. In comparison, the same plot of land in the Sahara desert contains about 100 times more water.</p><p>But a second study suggests other parts of the lunar surface also contain water — and potentially lots of it. Also publishing their findings in <a href="https://www.nature.com/articles/s41550-020-1198-9#_blank" target="_blank">Nature Astronomy</a> on Monday, the researchers used the Lunar Reconnaissance Orbiter to study "cold traps" near the moon's polar regions. These areas of the lunar surface are permanently covered in shadows. In fact, about 0.15 percent of the lunar surface is permanently shadowed, and it's here that water could remain frozen for millions of years.</p><p>Some of these permanently shadowed regions are huge, extending more than a kilometer wide. But others span just 1 cm. These smaller "micro cold traps" are much more abundant than previously thought, and they're spread out across more regions of the lunar surface, according to the new research.</p>

But if there is, it would mean that water would be much more accessible to astronauts, considering they wouldn't have to travel into deep, shadowy craters to extract water.</p><p>Greater accessibility to water would not only make it easier for astronauts to get drinking water, but could also enable them to generate rocket fuel and power.</p><p style="margin-left: 20px;">"Water is a valuable resource, for both scientific purposes and for use by our explorers," said Jacob Bleacher, chief exploration scientist in the advanced exploration systems division for NASA's Human Exploration and Operations Mission Directorate, in a statement. "If we can use the resources at the Moon, then we can carry less water and more equipment to help enable new scientific discoveries."</p>
The area of the brain that recognizes letters and words is ready for action right from the start of life.
- There's an area of the brain specializing in the recognition of letters and words.
- Neuroscientist wonder how this faculty develops since it would not be a trait associated with survival.
- fMRI scans reveal that this region is already connected to the brain's language centers in newborns.
Newborn and adult VWFAs<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNDU5MTY1MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0NjAwMzY2NX0.fDytqpINSvS8Lf6Xy7z9WAtqwp4FENjLzIZON0IoABg/img.jpg?width=980" id="cbab8" class="rm-shortcode" data-rm-shortcode-id="33228e0b095d0c486ff19de367fbb222" data-rm-shortcode-name="rebelmouse-image" />
Credit: Christian Bowen/Unsplash<p>Saygin, Li and their colleagues Heather Hansen and <a href="https://ccbbi.osu.edu/people/osher.6" target="_blank">David Osher</a> analyzed fMRI brain scans from 40 newborns and 40 adults that had been made as part of the <a href="http://www.developingconnectome.org/" target="_blank">Developing Human Connectome Project</a> and the <a href="http://www.humanconnectomeproject.org/" target="_blank">Human Connectome Project</a>, respectively.</p><p>The researchers found that even in the newborns — who were less than a week old — the VWFA was different from the visual cortex in that it already had connections to the language areas of the brain. While the VWFA and visual cortex share some characteristics — they both require high spatial resolution in order to accurately comprehend what they're seeing — the study reveals, says Saygin, that "The VWFA is specialized to see words even before we're exposed to them." We're primed for reading from the start, apparently.</p><p>Comparing the newborn VWFA to the adult VFWA did reveal <em>some</em> differences, however. "Our findings suggest that there likely needs to be further refinement in the VWFA as babies mature," Saygin explains. "Experience with spoken and written language will likely strengthen connections with specific aspects of the language circuit and further differentiate this region's function from its neighbors as a person gains literacy."</p>
Tracking the VWFA<p>Saygin's lab is currently attempting to better understand the sort of further VWFA development that may occur prior to reading, by studying the brain region in 3- and 4-year-olds. Her team is also interested in identifying the types of visual stimuli the VWFA responds to at those ages.</p><p>Learning more about the VWFA is more than just interesting — it may also help experts address reading and other cognitive issues. "Knowing what this region is doing at this early age," says Saygin, "will tell us a bit more about how the human brain can develop the ability to read and what may go wrong. It is important to track how this region of the brain becomes increasingly specialized."</p>
