Of three mobilization methods: robo calls, direct mail and phone calls, only live phone calls produce statistically significant mobilization effects among Latino voters.

The differential effect of various messages in five direct mail pieces are examined in terms of their relative effectiveness in mobilizing Asian American voters.

Partisan phone calls and mail, administered in different combinations. Neither the phone calls nor the mail used independently or together resulted in significant treatment effects.

In-language calls and English or bilingual direct mail are found to increase voter turnout among Asian Americans.

Three variations of identity-based direct mail are found to have little effect on turnout among Indian-Americans.
