What this means for each channel
Direct mail reaches almost everyone: 96% of 03801 homeowners have a deliverable mailing address. Mail is the only channel with no consent requirement, so it is the floor of any Portsmouth campaign.
Calling and texting reach about 29% with a connected mobile, but only 10% once you remove numbers on the National Do Not Call Registry. Texting a cold list also needs prior express written consent under the TCPA, so the DNC-clear figure is a calling figure, not a texting figure. See cold calling laws by state.
Email reaches about 45%. Cold email to consumers is legal under CAN-SPAM with an opt-out and a physical address, but deliverability on purchased consumer email is poor; treat it as a supporting touch.
