What email marketers say15Marketer opinions
Email marketer from Litmus shares that while link tracking is essential, using too many tracking parameters can make links appear suspicious to spam filters. They recommend keeping tracking parameters concise and relevant.
Email marketer from EmailAcademy explains that using link shorteners can negatively affect deliverability. Spammers often use link shorteners to hide malicious links, so using them can trigger spam filters. It's best to use full, transparent URLs.
Email marketer from ActiveCampaign shares that using secure (https) links is crucial for deliverability. ISPs and email clients prioritize secure connections, and using non-secure (http) links can trigger spam filters.
Email marketer from ZeroBounce explains that excessive redirects through multiple domains can raise suspicions and negatively impact your deliverability. Try to link directly to the final destination whenever possible.
Email marketer from Email Geeks shares that everything impacts reputation to an extent and that if you have tons of links that no one clicks, that could certainly cause issues, but that’s not really any different than an email with only a couple links that no one clicks.

Email marketer from Email Geeks shares there’s no scenario where I would give blanket advice to any sender to avoid links, regardless of whether you call them text links, CTA links, button links, image links, etc.. A link is a link, emails should have links if you expect people to engage and do something with it in almost all circumstances.
Email marketer from HubSpot explains that broken links can negatively impact your sender reputation over time as mailbox providers interpret it as neglect of your email program, suggesting that the email is not well maintained.

What the experts say4Expert opinions
Expert from Word to the Wise explains that linking to sites in 'bad neighborhoods' (sites with poor security, spammy content, or malicious intent) can negatively impact your sender reputation and deliverability. Email providers often correlate the reputation of linked domains with the sender's reputation.
