\section{Introduction}

Answer 1

我认为，您不想添加带标记的脚注，而只想添加附加脚注文本。因此请使用\footnotetext而不是\footnote：

\documentclass[11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[affil-it]{authblk}
\title{Title}

\date{}

\begin{document}

\author[1]{Caio}
\author[2]{Tizio}
\affil[1]{blabla}
\affil[2]{blablabla}

\footnotetext[2]{Corresponding author \\ \textit{E-mail addresses}: \texttt{[email protected]} (tizio),   Support from:}

\maketitle
\begin{abstract}

\end{abstract}

\section{Introduction}

\end{document}

Answer 2

应该\footnote在 之后\maketitle。

\documentclass[11pt]{article}
%\usepackage[utf8]{inputenc} % not needed with up-to-date LaTeX
\usepackage[affil-it]{authblk}

\title{Title}
\date{}

\begin{document}

\author[1]{Caio}
\author[2]{Tizio}
\affil[1]{blabla}
\affil[2]{blablabla}

\maketitle
\footnote[2]{Corresponding author \\ \textit{E-mail addresses}:
  \texttt{[email protected]} (tizio),   Support from:}

\begin{abstract}

\end{abstract}

\section{Introduction}

\end{document}
