Domestic abusers who control victims via social media or spy on them online could face up to five years in prison under a new law which is now in force.
The legislation will target those who subject spouses, partners and family members to psychological and emotional torment but stop short of violence.
It paves the way for charges in cases where there is evidence of repeated "controlling or coercive behaviour".
The Women's Aid charity said it was a "landmark moment" in tackling abuse.
The new law, brought into force in England and Wales, follows a Home Office consultation in which 85% of participants said the existing law did not provide sufficient protection.
It comes as Citizens Advice published figures showing a 24% rise in those seeking advice for domestic abuse.
