On the obvious merits of Email Verification services

There is considerable market demand for Email Address Verification (EAV). This is reflected by the fact that numerous companies have specialized in this field. For example, Return Path, Inc., the largest email intelligence and deliverability service provider, which works closely with numerous ESPs and ISPs, has recognized this fact and has started to collaborate with a major provider of EAV in order to offer its customers a benefit in email marketing.

List bombing: What does it mean and how to avoid it?

Recently, there’s some talk about list bombing. What does this actually mean?

While ISPs concentrate on attacks from a single IP (or IP range) or sending domain, listbombing uses various subscription forms for sending just a few mails from each.

Problem for the targeted address is, that a lot of mails are coming in in a small amount of time without consistent pattern – goal is to make the address unavailable for a specific time.

DOI doesn’t help here as well, because the DOI confirmation mail itself can be part of the attack and be used for it.

Deliverability in Brazil

The Carnival, the Lung of Earth, and of course football, that’s what comes to mind when we think about Brazil. However the view is slightly different from the inside, and specifically in email marketing.
