Email marketers just starting to think they see a sliver of recovery should keep this in mind: Data breaches continue to proliferate with depressing regularity, with email as a primary vector.
The number of reported breaches — 351 — is up 12% over fourth-quarter 2020, although that includes 59 incidents that occurred in that last quarter but were not reported until Q1 of this year, according to The Q1 analysis from Identity Theft Resource Center (ITRC).
Worse, 51 million individuals were affected in the first quarter, vs. 7.6 million in the last quarter of 2020. However, the total is down from 131.6 million in the first quarter of last year and 384.3 million in Q1 2019.

Financial services were second — there were 51 breaches hitting 1.7 million people, up from 35 breaches affecting 1.3 million in Q1 2020.

Government entities saw a falloff in attacks from 14 to 11. But 647,917 individuals were impacted, up from 21,993 in 2020.
