**Project summary**
Offering an apology is a strategy brands use in response to negative electronic word of mouth. However, its effectiveness is equivocal and may depend on its combination with other strategies. We investigated the use and the effectiveness of offering an apology in webcare conversations on Twitter using a mixed method approach. In Study 1, a corpus study was conducted to examine whether and how apologies occurred in 480 webcare conversations. In Study 2, we investigated the effectiveness of apologies separately and combined with a defensive and/or accommodative strategy. The experiment had a 2 (apology: present vs. absent) × 2 (defensive strategy: present vs. absent) × 2 (accommodative strategy: present vs. absent) between-subjects design. Flight passengers (N = 151) assessed a webcare response to a service failure on the airline’s reputation.
