DEVA now detects Disposable Email Addresses

DEVA (Dilli Email Validation API) now includes the ability to detect and flag Disposable a.k.a Throwaway a.k.a Temporary email addresses.

Disposable Email Address (DEA) is a temporary email address that is primarily intended for owners to hide their real email address. Users can request such an address from DEA providers like This address is ephemeral – it expires after a short period. It is used by real users to circumvent a registration process where email is required without providing their actual email address. Depending on the provider, some of these addresses can be public as well, i.e anyone can access its inbox. For ex: Click here to see the public inbox of

While initially invented to safeguard privacy, disposable addresses are now being actively abused to submit invalid data via web forms and such. Email broadcasting is a great marketing tool for genuine businesses who like to send periodic notifications to its list subscribers. Having throwaway email addresses in your recipient list means greater bounce rate given the temporary nature of such addresses. Given the frivolous nature of such addresses, its best to not have any DEA addresses in your subscription list.

Another example where such addresses can do harm to your business reputation is if your business is in the lead generation industry. Imagine selling a lead with email to your lead customers? Such an occurrence can do some serious damage to your relationship with them.

In summary, having disposable email addresses in new leads or opportunities can do serious harm to businesses. It may hurt your conversion rate and business reputation.

Starting today, we have integrated a validation rule in Dilli Email Validation API (DEVA) to detect disposable addresses and mark them as invalid. We actively maintain a list of 3000+ disposable email address providers that we check an email domain against to ensure its not disposable. Here are a few ways one can leverage DEVA to stop disposable addresses from making through to you:

‘Country Game’ – an Amazon Alexa Skill Game – Released

Dilli Labs is excited to announce the release of ‘Country Game‘ – An Amazon Alexa Skill Game that helps to build vocabulary of country names in kids and adults alike. To get started, simply enable ‘Country Game’ skill and say Alexa, play Country Game.

To enable this skill on your Amazon Alexa devices :

  1. Open the Alexa app, go to the menu, and select Skills.
  2. Browse for skills by category or use Search. This skill is named ‘Country Game‘. You can find it under the category Games, Trivia and Accessories -> Knowledge and Trivia.
  3. When you find a skill you want to use, select it to open the skill detail page. Then select the Enable Skill option.

Take turns saying country names with this skill. A country name should begin with the last letter of the previous country name spoken. For ex: if this skill responds with a country name ‘Sweden’, you have to say a country name starting with letter ‘N’ (last letter in word Sweden). When either you or the skill is unable to think of a country name, the game ends. The skill also randomly educates you about countries by telling a fun fact about them during the course of the game. For ex : if you say ‘Netherlands’, it may tell you a fun fact about it like “Did you know that around 20% of Netherlands is located below sea level?”

This skill keeps a score of your performance based on the number of countries you say in a game. You can also query your worldwide rank. The goal is to help you practice your vocabulary of country names in a fun and competitive way.


We developed this skill to enter into the Amazon Alexa Kids Challenge. This skill and game is kid-friendly.

Dilli Email Validation API : An Alternative to Mailgun

Mailgun is a great email address validation API that we once recommended and used. However, the recent decision by Mailgun to turn on the pricing switch has eroded a lot of its loyal users’ trust and confidence. Existing users are searching for alternatives to Mailgun for a cheaper and better solution. We were in a similar boat and hopped on to another email address validation service called Mailboxlayer which turned out to be very unreliable. This prompted us to create a new product in-house that will be far more superior than any email validation API in the market with fair pricing. Thus, Dilli Email Validation API (DEVA) was born.

DEVA is a simple API to check if a given email address is real without sending a verification email. Some of the factors used to determines validity of an email address are as follows :

  • Format Validation : DEVA ensures that email address is valid. Ex : email addresses with missing @ are not valid.
  • MX Records’ Existence : DEVA validates that MX records exist for the domain tied to the email address.
  • ESP (Email Service Provider) Grammar Rules: Ex : emails cannot have user part less than 4 characters. We learn new ESP grammar rules every now and then and incorporate into our validation algorithm.
  • Profanity Check : This is a distinguishing feature of DEVA. It checks email addresses for profanities and marks them invalid if found. Ex : f*** may be a valid email address but is marked invalid by DEVA because no sane person would use that.
  • Patterns : There are countless patterns we discovered while validating over 50,000 emails every month for our clients that are obviously invalid emails. Ex :,,, etc.  DEVA is constantly learning and building up the black listed patterns as our user base grows.
  • Disposable/Temporary address: Whether or not an email address is a disposable/temporary address such as @mailinator in which case its treated as invalid.
  • Role-based address: Whether or not an email address is role-based, like info@, help@, support@ in which case its treated as invalid.
  • Blacklisted Domains : Ex: is reserved and can’t be used in practice. Therefore, all emails having this domain are marked invalid by DEVA.

1000 email address validations will cost $8 with Mailgun but only $5 with DEVA.

Media Server (Red5) Hosting for existing HDFVR users

NuSoft recently announced that they will cease to support HDFVR – a popular flash based video recording platform for web applications – by end of 2017. You can find the official announcement on their blog here. NuSoft plans to instead sell Pipe – a new video recording platform that they plan to offer as SaaS (Software As A Service). The basic service sells for $50/mo . The ‘pro’ service for $200/mo. See more details here. They are also winding up their popular media server hosting service that cost b/w $15/month to $150/mo. This move disrupts services for existing users of HDFVR especially those leveraging the media server hosting services provided by NuSoft. Moving to Pipe is an expensive deal since they need to hire integration experts and also hop on to the monthly plan. Another alternative is to continue using HDFVR on your website with your own VPS/cloud media server. Dilli Labs is here to help you with this option. We now offer Red5 media server hosting for as low as $15/mo. We can also migrate your existing media to our server and configure your web application to move to new media server hosting. Interested ? Contact us now for more details at
