Next up, use an email client like Thunderbird. As to contacting Yahoo, that's on the web. Beware those fake 888 and 800 numbers out there. There are no Yahoo people here so do not expect help with that except advice on using better email software.
I added in yahoo mail signature 3 social media icons, one NEXT to each other, as shown here . But the icons come one BELOW each other, as seen here
Any suggestions on how I can fix this bug or who should I contact at yahoo to fix it?
