Calltime Text Follow-up Best Practices

1:1 text follow-ups is a quick way to engage with donors during a calltime session. With the texting landscape shifting rapidly due to strict new carrier algorithms, keeping a personal cell number out of spam jail requires a disciplined approach. Tips to navigate the new reality below.

🏆 1. The Golden Rule: Prior Interaction Only

Only text donors you actually just spoke with on the phone during the calltime session. Never "cold text" someone who didn't pick up, unless they are a close personal contact. If you promised to send a link during the call, that is your green light.

📱 2. Personalize Every Single Message

Carriers use "fingerprinting" algorithms to detect spam. If you send the exact same message to 20 people in a row, the carrier can assume you are a bot.

Do: Mention something specific from the call. "Great catching up about the education forum, John! Here is that link..."
Avoid: The text template is there to help kickstart a followup. Make sure to switch up your opening and closing phrasing every few texts

👤 3. Space Them Out (Human Pacing)

A human cannot physically type and send 15 texts in 30 seconds. If a personal line fires off rapid-fire messages, carrier firewalls flag it as automated traffic.

Take a breath between texts
Send the follow-up text immediately after hanging up with that specific person, rather than waiting until the end of a 3-hour call block to blast everyone at once

🔗 4. Use "Clean" Links

Links are the #1 trigger for carrier spam filters. Political domains are heavily scrutinized

Never use generic link shorteners: Avoid bit.ly, tinyurl, or rb.gy. Carriers automatically block these because scammers use them to hide malicious sites
Use the full URL: Send the direct Numero or campaign website link (e.g., (https://secure.numero.ai/contribute)). It looks more trustworthy to both the carrier and the recipient.

💳 5. Keep it Concise and "Normal"

Spam filters look for aggressive fundraising language.

Avoid excessive capitalization ("DONATE NOW"), multiple exclamation points, or dollar signs in the main text if you can avoid it ("We need $1,000 right now!")
Write like you are texting a colleague or a friend- "Hi Tiffany- It was great to chat with you yesterday. I loved hearing about your children and all the success they are having at college. We are looking forward to seeing you at Charlie's house next week for the fundraiser- I will be looking out for your cookies! If you were able to make that very generous contribution before the event here's the link https://secure.numero.ai/contribute/CharliesFundraiser. See you soon and TY!"
