„Warmbox on hädavajalik! Soojendusvalikud on täielikult kohandatavad ja kasutajaliides muudab selle kasutamise ülilihtsaks! Suurendasime kirjade kohalejõudmist 70% võrra“
„Warmbox päästis meie külmade e-kirjade kampaaniad ja suurendas meie haaret! Juba kuu ajaga jõudsime rämpspostist otse postkasti! Meeskonna nõuanded seadistamisel olid samuti väga väärtuslikud“
“Kõik meie müügimeeskonda lisanduvad töötajad soojendavad oma e-posti aadresse Warmboxiga mõne nädala jooksul, mis tagab külmade e-kirjade kampaaniate kõrge avamismäära. Jätkake samas vaimus!"
E-kirjade kohalejõudmine pole enam saladus. Oleme suutnud tuvastada, miks meie kirjad kohale ei jõudnud ja kuidas probleeme lahendada.
