When the two words email and blast combined together, it constitutes eblast. As a term eblast isn’t different from email blast, therefore, the question “”what is eblast”” isn’t different than what the email blast is? So whether it is eblast or an email blast, both generally denote when you blast email message to a huge volume of random recipients. The term is popularized within spamming communities, since they manipulate the volatile nature of mass-emails to promote scam offers of making money from home, investment opportunities, loan or credit offers and other non-solicited marketing emails.

It is definitely. Then, if email marketing refers to the process of sending commercial message to a group of recipient using the channel of email, and eblast indicates almost the same process, how email marketing is legitimate and eblast is negative way of marketing? Unlike the eblast to a list of random recipients, email marketing is targeted, largely acclaimed channel of sending permission based email messages. No marketer wants him to be tagged as spammer.

It is when you send emails to those who have asked to receive it from your side, instead of sending to those who are unaware of your identity, your domain and your company.  The scope of email marketing ties the sender to obtain the permission before adding the contact. The permission is generally obtained through the opt-in, subscription or signup forms. Hundreds of marketers and businesses use permission based email marketing channel to grow sales, strengthen the brands and improve communication with the clients.
Of-course it does. As long as you keep the permission of your recipient, and as long as you sending in compliance with spam act, your message are accepted and categorized as marketing emails. But as soon as the contact unsubscribes from your mailing list and you drop the permission, or you have used email harvesting process to obtain contact by purchasing, scraping or trading email lists, you may fall in the other category of spamming.
Yes it is, as the tools get more sophisticated and spammers turned fierce in their efforts of exploiting the legitimate channel of email marketing for illegal means. Legislation takes it course with the set of rules to limit the email spam. Spam laws bind legitimate marketers to accept some extra rules other than just the recipient’s permission. It includes, avoiding the use of misleading subject lines, offering recipients with a clear opt-out method, discontinue sending further email messages to the contacts that opted out from your mailing list, a clear message header, sender’s location information and few other details to ensure email message compliance.
Even though the contacts within the purchased list are said to be located in your targeted geography, or have been scraped from the niche relevant forum, and you aren’t sending the scam emails or Viagra offers, it still counts as eblast to a list of random recipients, unless you have the permission. Reconsider the way you approach email as marketing strategy.
